Functionalised carbon nano spheres modified electrode for simultaneous determination of dopamine and uric acid

SU-8 based pyrolytic carbon for the electrochemical detection of dopamine

“…2 Carbon materials are widely used in the detection of DA and recently the detection of physiological concentration (o700 nM 3,4 ) of DA has been achieved by many approaches. [5][6][7][8][9][10][11][12][13][14] Even though the detection of DA using carbon based materials is widely examined, the roles of different oxygen based functional groups in this process are not known unambiguously. Here we show that the strong interaction between the hydroxyl groups on the surface and DA facilitates the redox reactions of DA.…”

The doping level of boron-doped diamond electrodes affects the voltammetric sensing of uric acid

“…The electrochemical properties of such electrodes are in general strongly inuenced by non-uniform doping in diamond, boundary effects, varied ratios of graphite to diamond (sp 3 /sp 2 ), surface morphology and termination. 26,27 According to the literature survey, [9][10][11][12][13][14]21,[28][29][30][31][32][33][34][35][36][37][38] the utilization of a GCE and CPE as a working electrode is dominant in the electrochemical determination of UA. Until now, the methodology using a pencil graphite electrode (PGE) modied with over-oxidized poly(3,4-ethylenedioxythiophene) nanobers has been considered to be the most sensitive with the lowest LOD of 0.001 mM.…”

Unique Host Matrix to Disperse Pd Nanoparticles for Electrochemical Sensing of Morin: Sustainable Engineering Approach

“…Biomass-derived carbon nanospheres (CNSs) are promising porous carbon nanostructures which are generally used as adsorbents, catalyst support, and as electrodes in energy devices . There are very few reports on CNS-based electrode modifications for electroanalytical applications. , Carbon nanospheres are shells with quivering flakes following the curvature of a sphere. This leads to open fringed rims making the spheres chemically active .…”

“…This leads to open fringed rims making the spheres chemically active . These can be explored for various applications due to their enormous properties such as stability, compression withstanding ability, thermal insulation, biocompatibility, large surface area, and excellent conductivity. , Compared to other allotropes of carbon, CNSs possess distinct benefits, such as uniform particle size, unique surface properties, high porosity, and low toxicity resulting in exceptional biocompatibility . Such novel carbon materials can be considered for various practical applications.…”
