dc.description.abstract | Artificial enzymes have attracted considerable attention because of their significant advantages over natural enzymes. Herein, the authors report a simple hydrothermal strategy for producing a bimetallic metal - N-, S-doped carbon (NS-C@PtRu) hybrid derived from L-cysteine-mediated self-assembly of PtRu. The peroxidase-like activity and colloidal stability of the NS-C@PtRu are tuned by varying the amount of L-cysteine, the source material for the N-, S-doped carbon. The NS-C@PtRu exhibits good dispersibility, synergistic interactions (metal-metal, metal-carbon), non-metal (N, S) doping, more catalytic active sites, improved noble metallic catalyst performance, and high utilization efficiency. As an excellent peroxidase mimic, NS-C@PtRu catalyzes the oxidation of 3,3 ',5 ',5 '-tetramethylbenzidine (TMB), and Amplex Red (AR) substrates, producing colorimetric and fluorometric signals that offer efficient detection of H2O2. Furthermore, colorimetric and fluorometric cholesterol detection is proposed by combining cholesterol oxidase-catalyzed cholesterol oxidation with NS-C@PtRu-catalyzed TMB/AR oxidation. The fluorometric cholesterol sensor exhibited a lower limit of detection of 1.4 mu mol L-1 and rapid response, whereas the colorimetric sensor exhibited a wide detection range of 0.1-6 mmol L-1 and colorimetric changes that can be seen with the naked eyes. Both sensing methods demonstrated excellent selectivity and recovery in determining cholesterol in spiked human serum samples. | - |
