Ultrafine Pt–Ni bimetallic nanoparticles anchored on reduced graphene oxide nanocomposites for boosting electrochemical detection of dopamine in biological samples

Abstract

The present report demonstrates the development of a Pt–Ni/rGO composite electrochemical sensor for the detection of dopamine.

Integrated co-axial electrospinning for a single-step production of 1D aligned bimetallic carbon fibers@AuNPs–PtNPs/NiNPs–PtNPs towards H2 detection

“…The higher intensity of ID/IG peak for co-axial CFs@AuNPs-PtNPs may be due to the SERS enhancement upon introduction of plasmonic Au in the CFs based bimetallic nanosystem. 20,30 The structural and morphological analysis of the co-axial electrospun CFs based bimetallic nanosystem were further executed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis. The electric-field lines in the gap between Cu electrodes are drawn towards the electrode edges as seen in the electric field profile in Figure 4a.…”

Graphene and Carbon Nanotube‐based Electrochemical Sensing Platforms for Dopamine

“…G. Madhavi et al synthesized bimetallic nanoparticles deposited on GO using one-pot synthesis following a wet reflux approach. [146] Bimetallic nanoparticles are more significant in developing surface catalytic properties. The as-prepared PtÀ Ni/ rGO-modified GCE exhibited enhanced selectivity toward DA.…”

A Novel Electrochemical Sensor Based on Modified Carbon Paste Electrode with ZnO Nanorods for the Voltammetric Determination of Indole‐3‐acetic Acid in Plant Seed Extracts

“…Metal oxide nanoparticles (NPs) are characterized by their chemical stability, electrocatalytic activity, high electrical conductivity, structural robustness, biocompatibility, accessibility, simple synthesis, and relatively low cost. They are considered the most suitable modifiers applicable for the construction of voltammetric electrodes because of these attractive properties [23][24][25][26][27].…”
