In the present work, we proposed a novel naked-eye and turn-on fluorescence sensor based on the 5,10,15,20-(4-sulphonatophenyl) porphyrin (TPPS4)-Hg2+ system with short assay time and high sensitivity to detect glutathione (GSH) in real samples. The TPPS4 was the first time to detect GSH because of its high fluorescence quantum yield. The initial fluorescence from TPPS4 was quenched by Hg2+ with an...
A novel method for glutathione (GSH) detection in real blood sample with a nickel hexacyanoferrate (NiHCF) film modified Pt ultramicroelectrode (UME) was proposed. The electrochemical properties of NiHCF film modified Pt UME were improved by introducing cetyltrimethylammonium bromide (CTAB) and Au nanoparticles (AuNPs) into NiHCF film. The novel hybrid films (NiHCF/CTAB/AuNPs) were prepared by electrodepositing...
