Facile synthesis of dendritic-like CeO2/rGO composite and application for detection of uric acid and tryptophan simultaneously

An ultra-sensitive uric acid second generation biosensor based on chemical immobilization of uricase on functionalized multiwall carbon nanotube grafted palm oil fiber in the presence of a ferrocene mediator

“…Peak current ( I pa and I pc ) was found to vary linearly with the square root of the scan rate thus making the electron transfer a diffusion controlled process. 30…”

MoS2 nanosheets grown on bowl-shaped hollow carbon spheres as an efficient electrochemical sensor for ultrasensitive determination of nephrotoxic aristolochic acids in Chinese traditional herbs

“…An increase in the effective area of the electrode provides more space for the electrolyte solution to infiltrate, increasing the electrochemically active area, accelerating electron transfer, and increasing the current intensity. 35…”

Preparation of Multiwalled Carbon Nanotubes: Electrochemically Treated Pencil Graphite Electrodes for Nanomolar Detection of L‐Tryptophan in Complex Samples

“…PGE [s] L-Try in the presence of UA DPAdSV [ °'] 0.046 0.154-200.0 Human urine samples [46] CeO 2 /rGO-GCE [t] UA, L-Try LSV 0.006 0.06-100.0 Human serum samples [52] CDs/GCE [u] DA, UA, L-Try and TP DPV 0.11 1.0-65.0 Human serum [47] MWCNTs/pre-PGE [v] The developed method (DPAdSV) based on the MWCNTs/ pre-PGE sensor has good analytical performance in terms of repeatability, reproducibility, high selectivity sensitivity, and stability. The method offers the widest linear working range and lower detection limit (9.0 nM).…”
