| Research Abstract |
Thermoresponsive gold nanocomposites have been fabricated by conjunction of gold nanoparticles with thermoresponsive polymers and their colorimetric functions to sense sulfhydryl compounds have been also examined. The thermoresponsive gold nanocomposites exhibit disassembly by thermal stimuli, heating followed by cooling. Cysteine and homocysteine, sulfhydryl monopeptide, inhibit the disassembly while cysteinylglycine, sulfhydryl dipeptide, and glutathione, sulfhydryl tripeptides, promote the disassembly. Colorimetric quantification methods of cysteine, glutathione andγ-GPT are exploited based on the inhibition and promotion of the disassembly.
