Electrochemical determination of nitrite using silver nanoparticles modified electrode.
In this work, we report the fabrication and characterization of silver nanoelectrode ensembles (Ag-NEEs) on a glassy carbon electrode. For this purpose, Ag nanoparticles (NPs) were anchored to the mercaptopropyl functionalized MCM-41 type silica spheres utilizing the chemisorption property of Ag NPs by -SH groups. The successful anchoring of Ag NPs into the silica matrix is characterized by sev...
متن کاملSelective Electrochemical Nanosensor based on Modified Carbon Paste Electrode for Determination of NADH in the presence of Uric Acid
The electrochemical properties of a modified carbon paste electrode with the synthesized compound of 2,2'-[1,7–heptanediylbis(nitrilomethylidene)]-bis(4-hydroxyphenol) (DHBH) and graphite nanoparticle (GN) were studied by cyclic voltammetry (CV), chronoamperometry and differential pulse voltammetry (DPV) methods. The proposed electrode shows excellent electrocatalytic activity towards the oxida...
متن کاملStudy and Electrochemical Determination of Tyrosine at Graphene Nanosheets Composite Film Modified Glassy Carbon Electrode
A graphene nanosheets (GNS) film coated glassy carbon electrode (GCE) was fabricated for sensitive determination of tyrosine (Tyr). The GNS-based sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. The voltammetric techniques were employed to study electro-oxidation of Tyr. The results revealed that the modified electrode showed an electrocatalyt...
