Blood cancer causes a significant increase in the concentration of Leukocytes, which can be broken down through dielectrophoresis and electrochemical procedures. Therefore, the electric field plays an important role in the migration of leukocytes to high voltage areas. This is because different electrode arrangements produce varying electric field distributions. Furthermore, this study applied finite element methods to generate electric fields when electrodes with an AC voltage were applied to blood placed in a chamber. Therefore, in this study, variations of mediums and electrode arrangements were investigated, which led to the recommendation of 3 models. The objective was to investigate electrode arrangements that produce optimal electric field distribution for the three models to exhibit a booster of electric field distribution. The maximum electric field is generated close to the electrode (Z=2 mm and Z=92 mm) for any material (i.e. normal blood, B lymphocyte, and T lymphocyte) with values of 22.6 V/m and 23.47 V/m, 22.85 V/m and 22.97 V/m, and 24.88 V/m and 25.01 V/m. Based on principle, lymphocytes in the blood result in positive dielectrophoresis, since they migrate to a higher electric field close to the electrode, with enough input voltage to turn the electrochemical process on the leukocytes into electric current. Furthermore, this study provides new perspectives and ideas, which have not been revealed in previous studies on blood cancer therapy using the electric field of Ag electrode in blood cancer distribution.Keywords: blood cancer, dielectrophoresis, electric field, voltage, electrochemical, and cancer therapy.

The fabrication of silver (Ag) and gold (Au) thin film electrodes was successfully carried out using the DC sputtering deposition method. These thin film electrodes were able to detect the increase in serum albumin concentration that was used as a prognostic factor for leukemia. The simulation and the optical experimental analysis show that an increase in BSA concentration can increase the absorbance peak observed at a wavelength of 435 nm on hypoalbumin medium and 470 nm on normal concentration of serum albumin medium. The performance of the electrodes was electrochemically tested, in which it was shown that a decrease in oxidation and reduction peaks occurred with respect to an increase in BSA concentration. An oxidation peak was observed at a voltage of 0.5 V for the Ag thin film. For the Au, Au/Ag, and Ag/Au thin films, an oxidation peak was observed at a voltage of 1.0 V. The limits of detection (LODs) of the Ag, Ag/Au, Au, and Au/Ag thin films were 0.56, 0.24, 0.64, and 0.36 g/dL, respectively. Therefore, based on both the electrochemical and optical analysis, the Ag/Au thin film possessed the highest potential for prognosis monitoring of leukemia compared with the other Ag and Au thin films.

The development of silver (Ag) thin films and the fabrication of Ag nanosquare arrays with the use of an anodic aluminum oxide (AAO) template and leaf extracts were successfully carried out using the DC sputtering and spin coating deposition methods. Ag thin films and Ag nanosquare arrays are developed to monitor cancer prognosis due to the correlation between serum albumin levels and prognostic factors, as well as the binding of serum albumin to the surface of these electrodes. Nanosquare structures were fabricated using AAO templates with varying diameters and a gap distance between adjacent unit cells of 100 nm. The nanosquare array with a diameter of 250 nm and irradiated with electromagnetic waves with a wavelength of around 800 nm possessed the greatest electric field distribution compared to the other variations of diameters and wavelengths. The results of the absorption measurement and simulation showed a greater shift in absorption peak wavelength when carried out using the Ag nanosquare array. The absorption peak wavelengths of the Ag nanosquare array in normal blood and blood with cancer lymphocytes were 700–774 nm and 800–850 nm, respectively. The electrochemical test showed that the sensitivity values of the Ag thin-film electrode deposited using DC sputtering, the Ag thin-film electrode deposited using spin coating, and the Ag nanosquare array in detecting PBS+BSA concentration in the cyclic voltammetry (CV) experiment were 1.308 µA mM−1cm−2, 0.022 µA mM−1cm−2, and 39.917 µA mM−1cm−2, respectively. Meanwhile, the sensitivity values of the Ag thin film and the Ag nanosquare array in detecting the PBS+BSA concentration in the electrochemical impedance spectroscopy (EIS) measurement were 6593.76 Ohm·cm2/mM and 69,000 Ohm·cm2/mM, respectively. Thus, our analysis of the optical and electrochemical characteristics of Ag thin films and Ag nanosquare arrays showed that both can be used as an alternative biomedical technology to monitor the prognosis of blood cancer based on the concentration of serum albumin in blood.

The purpose of this study is to analyze the roles of industrial sectors in the Japanese national economy by using simple output multiplier, and simple household income multiplier, the analysis tools in Input-Output (IO) analysis. The analysis period of the study is 2011. The results show that, on the period of analysis, manufacturing sector had the highest simple output multiplier value. Therefore, one can argue that an additional final demand for the sector would generate the most attractive effect to the Japanese economy by using the multiplier on the period of analysis. Conversely, the lowest value of the multiplier was owned by the real estate sector in 2011. On the other hand, from the point of view of simple household income multiplier, the highest value was owned by the construction sector on the analysis period. This result indicates that an additional yen of final demand for the sector would generate the highest new household income on the period of analysis. On the contrary, as with the previous multiplier, the real estate sector had the lowest simple household income multiplier value in 2011.

3D printing technology was capable of fabricating phantoms to enhance quality assurance in radiation therapy. The ideal phantom has properties equivalent to the real tissue. However, 3D Printing has the limits to mimicking the attenuation properties of various tissues because during 3D printing there can be only one type of material. The purpose of this study was to evaluate the effect of infill percentage and infill patterns of 3D printing technology to simulate various types of tissue. This study used 25 samples measuring 5 × 5 × 1 cm3 from PETG material. The 20 samples were printed using variations infill percentages from 5 - 100% and the infill pattern in lines. The five samples were then printed with the infill percentage constant at 50% and used the infill pattern triangles, grid, gyroid, octet, and concentric. We used Computed Tomography (CT) to determine the Hounsfield Unit (HU) value for each sample and evaluated the suitability of each sample for phantom applications in radiation therapy and radiology. However, none of the samples was able to simulate compact bone. As a result, we found that PETG material could simulate the properties of soft tissue, fat, lung, kidney, liver, pancreas, and spongy bone. Thus, the study had shown promising potential for the fabrication of the anthropomorphic phantom of radiation therapy.

Finite Differential Time Domain widely used in electrical analysis and design electromagnetic field. A two dimensional modeling ZnO Nanostructure was established and approach to find a low cost glucose sensor and derived as a diabetes disease detector. Authors were interested with a PtCu as a good glucose sensor and want to find an alternative low cost glucose sensor. This letter shows that ZnO nanostructure has a linear correlation of Electromagnetic Field distribution with PtCu when given a laser with wavelength 350 - 700 nm. Electric field value decrease when EM wave given at 450 - 550 nm both of ZnO and PtCu and tend to steady at wavelength 600 nm more. In this letter we propose ZnO as a low cost glucose sensor with high sensitivity.

Zinc oxide is material compatible for biosensors, which has good properties such as low cost, high stability and wide band gap.

Characterization used XRD to determine the crystalline phase, The Zinc oxide thin film is characterized by a cyclic voltammetry (CV) with scan rate of 5mV / s and different concentration phosphate buffered saline solution. A wurtzite structure of Zinc oxide has been acquired the crystal size 233 nm by using debye scherer equation (rietvield method) and optical band gap obtained 3.17 eV.

Insufficient reduction capability and scanty active substance limit the application of LaFeO3 (LFO) in the field of photoelectrochemical (PEC) water splitting. This work demonstrates a judicious combination of LFO/Nafion composite to improve the PEC performance by a unique dip-coating method on the FTO. The photocurrent density of the LFO electrode coated with two layers Nafion increased to −23.9 μA cm−2 at 0.47 V versus RHE, which is 4.1 times that of the pristine LFO. Based on the experimental data and theoretical analysis, the improvement of the PEC properties is attributed to the construction of organic/inorganic units, which would enable strong electronic coupling and favor interfacial charge transfer, resulting in a 30 mV downward shift of its flat band potential. Thus, the conduction band gets closer to the proton reduction potential of H+ to H2 after decoration with Nafion, resulting in a stronger photogenerated electron reduction ability. Our study provides insights that organic materials modify semiconductor photoelectrodes for accelerating charge kinetics.

Diabetes is one of the most common diseases globally that is caused by glucose. Glucose binds to hemoglobin in Red Blood Cell in minor unit Haemoglobin A1c (HbA1c). A large HbA1c concentration in blood indicates that a person has diabetes. This study has the aim to determine the different electric field distribution along with the different concentrations of glucose on blood. Nanorod arrays in this research produced from previous research with AAO template, then ZnO deposited inside with geometry size 150x150x500 nm are irradiated with light in the UV Vis wavelength range. The medium in this research was on a blood model with different glucose concentrations which have low glucose (hypoglycemia), normal glucose blood, and high glucose concentration (hyperglycemia). Electric field distribution depends on medium and wavelength analysed to determine the optimal value for Glucose-Blood monitoring. The result shows that the distribution pattern of the electric field at ZnO nanorod arrays with different mediums has a different value. It indicated from electric field maximum peak, the color contour of electric field distribution, and the absorbance of ZnO nanorod arrays. Finally, we got the optimal wavelength use for glucose blood monitoring was on wavelength around 400 nm.

Non-invasive cancer treatment has the potential to eliminate infection and scar formation associated with surgery to minimize side effects. Light stimulation can use for treatment to increase efficiency, reduce treatment costs, eliminate infection, etc. Magnetic fields can improve blood circulation in tissues and stimulate the body’s metabolism. The magnetic field can induce joule heating and expand the blood vessels of cancerous tumors. These blood vessels increase the possibility of excess oxygen to enter the tumor creating obstacles to the survival of oxygen-rich cancers. In this study, we investigate finite difference times domain (FTDT) simulation of magnetic field in normal and blood cancer. The low frequency with range 10-106 is used in this study. The maximum magnetic field for normal blood and CLL1 is 400 nm and 250 nm in 125 cm electrode size. While for 50 nm electrode size, the maximum magnetic field in normal blood and CLL 1 is 400 nm and 300 nm. But there The maximum magnetic field for normal blood and CLL1 is 400 nm and 250 nm in 125 cm electrode size. While for 50 nm electrode size, the maximum magnetic field in normal blood and CLL 1 is 400 nm and 300 nm. But there is no peak for blood cancer in final stage CLL2.

P-type Cu 2 O has long been regarded as an advantageous material in photoelectrochemistry, owing to the suitable band gap structure and cost-effective production. However, such promising material is suffering from corrosion in aqueous electrolytes. To address this issue and attain a high photoelectrochemical performance, protective oxide layers and expensive catalysts have to be adopted. The complicacy of such additional procedures, however, limits the further applications. Instead of utilizing surface protecting oxide layers and expensive catalysts, herein, we report that the surface treatment of Cu 2 O photocathodes using trisodium citrate (TSC) could also greatly enhance the photoelectrochemical performance. In comparison with the electrode without TSC, the photocathode of FTO/Au/Cu 2 O/TSC/TiO 2 /Pt presents a pronounced increment in photocurrent with a factor of about 2. Therefore, this paper provides a novel but convenient methodology to optimize the performance of solar energy conversion systems employing p-type Cu 2 O by modifying the surface with functional molecules.

Above normal concentrations of leukocyte can indicate blood cancer in humans. This study uses a finite difference time domain (FDTD) based on the Ag nanostructure array experiment from previous study. The influence of leukocyte and blood medium and also Ag nanostructures dimensions the on the pattern of electric field distributions in Ag nanostructure arrays was described on this study. The electric field distribution and transmittance of Ag nanostructure arrays using different medium was analysed. The electric field in Ag nanosquare with side size 50 nm irradiated with electromagnetic wave at a wavelength of 350 nm has value 1.78 × 10−5 V/m and has the highest electric field value compared to the other dimensions and wavelengths of electromagnetic wave. The maximum difference value of transmittance Ag nanosquare array between blood and leukocyte is 8.06 a.u. This value is resulted from Ag nanosquare with side size 50 nm irradiated with electromagnetic wave at a wavelength of 250 nm. These result provide an initial interpretation of optimum wavelength of electromagnetic wave and size of Ag nanosquare arrays for therapy and detection of blood cancer.

Blood carrying more leukocytes can induce differences in electrical and magnetic properties. This work describes the effect of leukocyte concentration on the distribution of electric fields. The finite difference time domain approach of electric field distribution using normal blood and leukocyte has been analyzed. The electric field in the blood and leukocytes have the same peak at a wavelength of 400nm. Ag nanosquare with dimensions of 350×350nm2 in blood and leukocyte medium has a different maximum electric field of 7.35 × 10−7V/m with a peak wavelength difference of 0.22nm. The results of this work are beneficial to expected and provide an interpretation of blood cancer detection using an Ag nanosquare arrays sensor.

In view of the disadvantages of the conventional photocathodic materials, we focus on exploiting new candidates for a high-efficiency photoelectrochemical (PEC) system. Herein, we report on the fabrication of CuBi2O4 (CBO) films on FTO (fluorine doped tin oxide) and FTO/Au substrates, respectively, through the electrochemical deposition approach. It was observed that the presence of a Au thin layer could help to improve the crystal quality of the grown CBO films, promote the separation of photo-generated charges in the corresponding material and reduce the resistance of the system. In comparison with the FTO/CBO, the FTO/Au/CBO photocathode presents a remarkable improvement in the photocurrent, from −0.23 mA cm−2 to −0.50 mA cm−2 at 0.1 V vs. RHE. After optimizing the PEC system by depositing Pt nanoparticles on the CBO films, the plateau photocurrent was further amplified to −1.24 mA cm−2. These data indicate an attractive p-type material in photoelectrochemistry, without concern for the corrosion problem in aqueous electrolytes.

The monitoring heart rate by vibration sensor based on self-mixing interferometry (SMI) had been done. Experimental schemes and the performance of vibration sensor based on SMI as a function of frequency and amplitude of human heart rate signals had been examined. The vibration sensor consists of a laser diode as a light source (λ = 785 nm) with integrated detector, a mirror as a vibrating target, and a simulated heart signal from ECG generator. ECG generator signals and audio amplifier are adjusted in frequencies of 1-100 kHz. The result showed that the feedback parameter of SMI signal could be identified at frequency 50 Hz. The heart signal was shown clearly at frequency 100 kHz.

Heart Rate is important information about the physiological and psychological condition of human. The pulse rate is directly related to the heart activity because of the impact of the volume changing of blood correlated to the heart which pumps blood throughout the body periodically. Heart rate measurement is used generally ECG (Electrocardiogram) or Blood Pressure Measurement in the medical world. In this paper the ratio of the heart rate is analyzed by using a technique photoplethysmography and optical sensor based on self-mixing interferometry. A typical self-mixing configuration consist of a laser diode as a light source (LD, 785 nm) and the photodetector which integrated in the package. Photoplethysmography consist of infrared (IR, 940 nm) acts as source of light, photodiode as a photo-detector, PPG circuit, arduino and PC. Photoplethysmography is non-invasive optical technique that can used to detect blood volume changes in the microvascular bed of tissue. The result show that human heart rate signals can be detected using the SMI method with a frequency of 100 kHz and input current 50 mA, but using PPG method the human heart signal was detected in the amplitude range of 2,070 to 2,080 mV.
