Recently, green synthesis has attracted much attention from researchers and has been regarded as a viable alternative to chemical and physical methods. The Terminalia chebula seeds extract mediated magnetic iron oxide nanoparticle was synthesized in this work. As it is rich in various phytochemical substances, including chebulic acid, chebulagic, and carilagin acid, as well as antioxidants such phloroglucinol, pyrogallic, vanillic, and caffeic acid. Further, after synthesis, the nanoparticles were then characterized using advanced techniques like Fourier Transform infrared (FT-IR), UV-Visible Spectroscopy, Transmission Electron Microscopy (TEM), and Scanning Electron Microscopy (SEM) to evaluate its structural, optical, and morphological features. Synthesized iron oxide nanoparticles have proven to cause excellent dye degradation properties for most industrial dyes that harm the environment and living beings, as well as show unique magnetic, catalytic, optical, sorption, and other properties, allowing them to be functionalized in a number of advanced nano applications. Owing to this, the biologically synthesized magnetic iron oxide nanoparticles will be studied for electrochemical biosensing of pesticides, which threatens the ecosystem and human health.

In this work, we have utilized leaves extract of Argyreia Nervosa (AN) to synthesize magnetic iron oxide nanoparticles by using the mixed precursor salt (ferric chloride and ferrous sulphate). After nanoparticles synthesis, it was initially characterized using Fourier Transform Infrared spectroscopy (FT-IR), UV–visible spectrophotometry (UV-Visible), Transmission Electron Microscope (TEM), and Scanning Electron Microscope (SEM). Further, characterization in this work is needed, namely AFM, XRD, and electrochemical studies (Differential Pulse Voltammetry (DPV) and Cyclic Voltammetry (CV)). The desired work is novel for synthesizing magnetic iron nanoparticles and their utilization for fabricating electrochemical biosensor devices for pesticide detection. Hence, in this study, we have focused on synthesizing magnetic iron oxide nanoparticles via the biogenic route of synthesis for fabricating an enzyme-biosensor for the determination of pesticides, which will open a new avenue for developing nanobiosensing devices through a greener and sustainable approach that is green/bioinspired/bioderived synthesis of nanomaterials that utilizes phytochemicals.

Nanotechnology is a potentially growing domain of science, and breakthroughs in this have resulted in significant advances in numerous domains, such as agricultural, environmental, sensors, biomedical, etc. The current study focuses on the biogenic synthesis of copper oxide nanoparticles (CuO NPs) using latex of Ficus religiosa. We utilized stem latex to present an environmentally friendly approach for the biogenic synthesis of CuO NPs. The UV–Visible spectrophotometry (UV-Visible) technique confirms the initial formation of nanoparticles based on the visible color shift and is later confirmed by the Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscope (TEM), and Scanning Electron Microscope (SEM). Furthermore, the biogenic CuO NPs will next be evaluated by X-Ray Diffraction, Zeta-Potential, Atomic Force Microscopy, etc. The proposed work will be unique as our objective is to utilize biogenic CuO NPs to fabricate electrochemical biosensor devices for pesticide detection. Hence, it will open a new avenue for developing nanobiosening devices through a greener and sustainable approach that utilizes phytochemicals, not toxic chemicals.
