We demonstrate a simple enzyme-free electrochemical sensor for tyrosine (Tyr) detection,
based on the enhanced catalytical activity of two-dimensional molybdenum disulphide …

Tyrosine (Ty) is an important amino acid that converts to levodopa (L-DOPA) which is used
for treatment of Parkinson's disease (PD). Also, there is a correlation between UA levels and …

A carbon paste electrode (CPE) was modified with graphene and ethyl 2-(4-ferrocenyl-[1, 2,
3] triazol-1-yl) acetate (EFTA) and used for electrocatalytic oxidation of levodopa. Under …

CeO 2-SnO 2 nanocomposites were synthesized by simple chemical precipitation method.
The composites were characterized by XRD, UV–vis, SEM, FE-SEM, HR-TEM, FT-IR and FT …

In the present work, an electrochemical sensor based on reduced graphene oxide/β-
cyclodextrin/silver nanoparticle/polyoxometalate (RGO–CD–AgNP–POM) was developed for …

Two-dimensional molybdenum disulphide nanosheets (2D-MoS 2) were prepared by liquid-
phase exfoliation and used to modify screen-printed carbon electrodes (SPCE), in order to …

The authors report that the peroxidase-like activity of Au@ Pt core-shell nanohybrids (Au@
PtNHs) is selectively inhibited by cysteine. This finding has led to a highly sensitive …
