SiC nanoparticles-modified glassy carbon electrodes for simultaneous determination of purine and pyrimidine DNA bases

A High Performance Electrochemical Biosensing Platform for Glucose Detection and IgE Aptasensing Based on Fe3O4/Reduced Graphene Oxide Nanocomposite

“…On the basis of excellent electrochemical features of chemically reduced GO (CR‐GO), Zhou and co‐workers applied CR‐GO modified GC electrode to simultaneously detecting all four free bases of DNA 41. More recently, exploiting the promising properties of silicon carbide semiconductor NPs, we proposed a sensitive and selective electrochemical sensor for the simultaneous detection of DNA free bases with a SiC NPs modified GC electrode 42. Figure 5 (A–D) shows the DPVs at the Fe 3 O 4 /r‐GO/GC electrode for three successive additions of G, A, T and C, respectively.…”

Silicon Carbide: A Biocompatible Semiconductor Used in Advanced Biosensors and BioMEMS/NEMS

“…The effects of different parameters such as the thickness of the SiC layer, pulse amplitude, scan rate, supporting electrolyte composition and pH were optimized to obtain the best peak potential separation and higher sensitivity. The modified electrode can be used for simultaneous detection of purine and pyrimidine bases without any separation or pretreatment processes and may be used as a DNA biosensor in real samples [30].Caputo et al [31] reported on biomolecule detection based on a two-color amorphous silicon photosensor. The device design has been optimized in order to maximize the spectral match between the sensor responses and the emission spectra of the fluorochromes.…”

Influence of activated charcoal on the structural and morphological characteristics of ceramic based on silicon oxycarbide (SiOC): A promising approach to obtain a new electrochemical sensing platform

“…Owing to its semiconductor character, thermal and mechanical properties, silicon carbide has already been studied as electrochemical sensor for electrocatalytic detection of insulin [22], dopamine in the presence of ascorbic and uric acids [23], as well as DNA bases [24]. In this way, a comparison between preceramic polymers containing different amounts of aromatic carbons that will result in SiCO with distinct C free contents is relevant.…”
