“…46 Furthermore, Aghebati-Maleki et al reported on the UV absorption spectra in the 220–650 nm region without a maxima of the chemically-synthesized MgO NPs. 47 The present data are compatible with the previously reported B-MgO NPs showing a distinctive absorption band of MgO up to 800 nm. There are no sharp peak observed, confirming that the nanoparticles are of different sizes.…”

BACKGROUNDThis study focuses on the fabrication of a biosensor for the electrocatalytic and selective hydrogen peroxide (H2O2) recognition with bovine liver catalase (CAT) immobilized over cysteine (c) modified zinc oxide nanoparticles/graphene oxide (c‐ZnO/GO) interface. The selectivity and sensitivity of the biosensor were augmented by the use of CAT and GO, respectively. The problem of CAT activity inhibition by GO was specifically solved by the incorporation of ZnO. Also, the cystine functionalization helped in better immobilization of CAT.RESULTSThis unique approach was first validated with in silico computations that calculated the binding affinities to study the interactions between different components of the biosensor. The electrochemical studies confirmed the step‐by‐step modification of the sensor, where along with GO, c‐ZnO nanoparticles also showed excellent electro conductivity by fundamentally improving the peak currents towards H2O2. The proposed bio‐nano interface exhibited superb electrocatalytic performance and specific detection capability for H2O2 across a broad linear range (0.1 to 40 μM), featuring a low detection threshold (0.1 μM), as well as commendable reproducibility and storage durability. Furthermore, the biosensor yielded satisfactory outcomes for H2O2 detection in milk samples.CONCLUSIONSensing performance of nano‐bio interfaces can be augmented by using the appropriate nano‐composites and their efficacy confirmed through computational techniques such as molecular docking. The biosensor can be further repurposed into a wearable device by integration with lab‐on‐a‐chip platforms.This article is protected by copyright. All rights reserved.

Nanoparticles and nanotechnology developments continue to advance the livelihood of humankind. However, health challenges due to microorganisms and cancerous cells continue to threaten many people’s lives globally. Therefore, new technological interventions are of great importance. The phytochemicals present in medicinal plants are suggested as biocompatible, cost-effective, and regenerative sources that can be utilized for the green synthesis of nanoparticles. Different plant extracts with various phytochemical constituents can form nanoparticles with specific shapes, sizes, and optical properties. This review focuses on advances in green nanotechnology and provides details on reliable synthetic routes toward medically and biocompatible relevant metallic nanoparticles. We cover a wide range of applications that use phytonanoparticles with an in-depth look at what makes these materials interesting. The study also provides details of the literature on the interventions made in phytonanotechnology for the production of plant-mediated synthesis and capped metallic nanoparticles and their applications in various industries. It was observed that a variety of plants have been well studied, and detailed findings have been reported; however, the study of Phyllanthus is still in its early stages, and more needs to be uncovered.
