Bioderived Magnetic Iron Oxide Nanoparticles from Leaf Extract of Argyreia Nervosa for Electrochemical Biosensing of Pesticide

Abstract

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.

Smart and intelligent optical materials for sensing applications

“…This in turn could enable point-of-care testing and determine agricultural and environmental toxins, namely heavy metals, pesticides, herbicides, etc. In addition, these optical materials could reduce the cost of sensors and make the sensors portable, sensitive, selective, reusable, and simple [8][9][10][11][12]. Therefore, this special issue (SI) entitled 'Smart and intelligent optical materials for sensing applications', published by Luminescence, Wiley focuses on the recent advancement of smart and intelligent optical materials for the fabrication of sensor technology and its use in numerous fields such as pharmaceutical, biomedical, and environmental areas.…”
