The present manuscript portrays environmental benign, cost‐effective and energy efficient green route way to synthesize Mg−Zn ferrite nanoparticles [Mg0.05Zn0.05Fe2O4 NPs] using Ocimum Basilicum leaf extract [OBLE]. X‐ray diffraction (XRD) analysis revealed that Ocimum Basilicum leaf extract mediated Mg−Zn ferrite nanoparticles [OBLE@Mg−Zn NPs] exhibit face centred cubic crystallinity with space group Fd3‾m ${{\rm F}{\rm d}\bar{3}{\rm m}}$ as confirmed by Rietveld refinement studies. Microstructural analysis illustrated uniform surface morphology with well interlinked grain with an average grain size of 35.6±0.12 nm. FTIR spectra showed existence of hydroxyl −OH group at 3403 cm−1 and C=C vibration at 2345 cm−1. Magnetic hysteresis loop (M−H loop) confirmed the superparamagnetic behaviour of OBLE@Mg−Zn NPs. Cytotoxic activity of OBLE@Mg−Zn NPs was carried out against breast cancer cell line MDA‐MB‐231. Dose dependent cell viability of cancerous cells depicted cytotoxic potential of OBLE@Mg−Zn NPs.

The development of new tools with outstanding performance for monitoring neurotransmitters is a challenging task in neuroscience. Electrochemical probes have attracted tremendous attention for the identification and quantification of neurotransmitters, owing to their demonstrated potential for quick response, real‐time measurements, elevated selectivity and sensitivity. In this Review, we have focused on the recent developments of carbon nanotube (CNT)‐based electrochemical sensors for dopamine detection. The use of CNTs is beneficial for this task, because of their high tensile strength, flexibility, good electrical conductivity, and low thermal expansion coefficient. Therefore, electrochemical sensing approaches with CNTs have opened the door for researchers working towards neurobiomedical applications. CNTs on the fishing job: The detection of the neurotransmitter dopamine by using conductive and tensile non‐metallic carbon nanotubes (CNTs) is described. Three main types of materials have been developed in this regard, including metal or metal oxide nanoparticles supported on CNTs, polymer‐coated CNTs, and functionalized CNTs grown on glassy carbon electrodes.

The Cover Feature shows the detection of neurotransmitter dopamine in the presence of interfering chemical species, such as ascorbic acid and serotonin, using carbon nanotube (CNT)‐based materials. The highly conducting nature of functionalized CNTs, with large tensile strength, makes them an ideal non‐metallic material for the development of biosensors. Other modifications such as depositing metal or metal‐oxide nanoparticles on the CNT surface and coating polymers onto them can significantly increase their properties towards the detection of dopamine. Cyclic voltammetry can detect dopamine through its redox behavior over a wide potential range by using modified CNT electrodes. More information can be found in the Review by N. Gupta and co‐workers on page 274 in Issue 2, 2019 (DOI: 10.1002/celc.201801319). [ABSTRACT FROM AUTHOR]
