WebDec 15, 2015 · It is the first report to explore colorimetric assays for biothiols with high sensitivity and selectivity against non-thiol-containing amino acids, on the basis of thiol-induced inhibition of peroxidase-like activities of metal nanoparticles. By using Au2Pt1 nanozyme, the limit of detection (LOD) is 3.5 nM for cysteine and 1.6 nM for homocysteine. WebJul 5, 2024 · Biothiols play important roles in biological processes. In this study, a novel sensor array-based method was proposed to detect and differentiate biothiols. The sensor array was constructed using three kinds of Ag + -sensitive carbon nanodots (CDs). The CDs were synthesized with amino acids and urea as carbon sources via a simple microwave …
