Sensitive sulfide sensor with a trypsin-stabilized gold nanocluster.
In this work, we synthesized a trypsin-stabilized fluorescent gold nanocluster. It was found that sulfide interacted with the nanocluster, which could result in significant fluorescence quenching. With this quenching effect, a fluorescence sulfide sensor was developed. This sensor responded linearly to sulfide in the range of 50 nM to 8 μM, and was capable of detecting sulfide as low as 5.5 nM....
متن کاملTrypsin-stabilized fluorescent gold nanocluster for sensitive and selective Hg2+ detection.
We report on trypsin-stabilized fluorescent gold nanoclusters (Au NCs) for the sensitive and selective detection of Hg(2+) ions. The Au NCs have an average size of 1 nm and show a red emission at 645 nm. The photostable properties of the trypsin-stabilized Au NCs were examined, and their photochemical stability was found to be similar to that of CdSe quantum dots. The fluorescence was particula...
متن کاملGold nanocluster-catalyzed selective oxidation of sulfide to sulfoxide.
Thiolate-protected gold nanoclusters are explored for catalytic application in the selective oxidation of sulfide to sulfoxide by PhIO. The TiO(2)-supported Au(25)(SR)(18) nanocluster catalysts give rise to high catalytic activity (e.g.∼97% conv. of Ph-S-CH(3) and ∼92% selectivity for Ph-S(=O)-CH(3) sulfoxide) and show excellent recyclability in the sulfoxidation process.
متن کاملLabel-Free Fluorescent Detection of Trypsin Activity Based on DNA-Stabilized Silver Nanocluster-Peptide Conjugates
Trypsin is important during the regulation of pancreatic exocrine function. The detection of trypsin activity is currently limited because of the need for the substrate to be labeled with a fluorescent tag. A label-free fluorescent method has been developed to monitor trypsin activity. The designed peptide probe consists of six arginine molecules and a cysteine terminus and can be conjugated to...
