Wang, Peng published the artcileRational design of dual-functional peptide-based chemosensor for sequential detection of Ag+ (AgNPs) and S2- ions by fluorescent and colorimetric changes and its application in live cells, real water samples and test strips, Application of Fmoc-Pro-OH, the publication is Microchemical Journal (2022), 107326, database is CAplus.
A novel bifunctional chemosensor L with excellent fluorescent group FITC labeled at tetrapeptide (CysProGlyHis-NH2) was designed and developed. L exhibited fluorescent quenching response and unique visual color change for Ag+ and AgNPs in aqueous solution The stoichiometry between L and Ag+ was confirmed to be 1:1 based on fluorescent titration, Job¡äs plot, ESI-HRMS and theor. calculation studies. In particular, the limit of detection (LOD) of L for the detection of Ag+ and AgNPs were calculated as 3.35 nM and 4.57 nM, resp. In addition, the L-Ag complex as a new relay chemosensor could be highly selective detection of S2-via obvious color and fluorescence changes, which could be monitored by the naked eye. The LOD for S2- was as low as to be 28.17 nM with high sensitivity. Furthermore, L indicated a rapid response (within 50 s), exciting circularity (more than 10 times) and wide pH response range (6 ? 12). Moreover, in view of excellent stability, low cytotoxicity and biocompatibility, we further successfully applied L for Ag+, AgNPs and S2- detection and imaging in living cells, real water samples and test strips.
