TL;DR: A novel, highly sensitive amperometric biosensor, based on electrodeposition of gold-platinum bimetallic nanoparticles onto 3-aminopropyltriethoxy silane modified glassy carbon electrode for the detection of paraoxon ethyl, aldicarb, and sarin has been developed.
Journal ArticleDOI
A new glucose sensor based on encapsulated glucose oxidase within organically modified sol–gel glass
TL;DR: In this article, a non-mediated glucose biosensor is reported based on encapsulated glucose oxidase (GOD) within the composite sol-gel glass, which is prepared using optimum concentrations of 3-aminopropyltriethoxy silane, 2-(3, 4-epoxycyclohexyl)-ethyltrimethoxysilane, GOD dissolved in double distilled water and HCl.
Journal ArticleDOI
Studies on the electrochemical performance of glucose biosensor based on ferrocene encapsulated ORMOSIL and glucose oxidase modified graphite paste electrode
TL;DR: The sensitivity, response time and linearity of the new glucose biosensor are found to be excellent over earlier reported glucose bios sensor and the practical usability of new glucose sensor has been compared with earlier developed glucose sensor.
Journal ArticleDOI
A New Glucose Biosensor Based on Sandwich Configuration of Organically Modified Sol-Gel Glass
TL;DR: In this paper, a new glucose biosensor was developed based on the sandwich configuration of organically modified sol-gel glasses, which was used to develop glucose biosensors that differ in absence (A) and the presence of graphite powder [particle size 1-2 μ] (B).
Journal ArticleDOI
Electrochemical immunosensor for botulinum neurotoxin type-E using covalently ordered graphene nanosheets modified electrodes and gold nanoparticles-enzyme conjugate
TL;DR: The developed electrochemical immunosensor could detect BoNT/E with linear range from 10PG/ml to 10ng/ml with the minimum detection limit of 5.0pg/ml and total analysis time of 65min and was successfully evaluated against food samples.
