Gold nanoparticle-based sensing platform of hydrazine, sulfite, and nitrite for food safety and environmental monitoring
Background: A facile and sensitive electrochemical sensor platform has been explored based on gold nanoparticles (Au NPs) dispersed in amine-functionalized three-dimensional (3D) silicate sol–gel network for ((aminopropyl)triethoxysilane (APS)-Au NPs) for multi-analytes such as hydrazine, sulfite, and nitrite. Methods: Au NPs dispersed silicate network was prepared via a single-step chemical re...
متن کاملElectrodeposited Graphene and Silver Nanoparticles Modified Electrode for Direct Electrochemistry and Electrocatalysis of Hemoglobin
By using a 1-butylpyridinium hexafluorophosphate based carbon ionic liquid electrode (CILE) as the working electrode, graphene (GR) nanosheets and silver nanoparticles (Ag NPs) were step by step electrodeposited on the surface of the CILE with potentiostatic method. The fabricated Ag/GR/CILE was used as a new platform for protein electrochemistry and hemoglobin (Hb) was immobilized on its surfa...

15 صفحه اولDirect Electrochemistry of Hemoglobin on Graphene Nanosheet-based Modified Electrode and Its Electrocatalysis to Nitrite
A novel amperometric nitrite (NO2 − ) sensor was developed based on immobilization of hemoglobin (Hb) on a graphene nanosheet modified electrode by chitosan-N, N-Dimethylformamide (CS-DMF) hydrogel. The surface morphologies of the modified electrode were characterized by SEM, and direct electrochemistry of Hb on the graphene nanosheet-based electrode were investigated by cyclic voltammetry. The...
