CdTe nanocrystals as luminescent probes for detecting ATP, folic acid and l-cysteine in aqueous solution

11-Mercaptoundecanoic acid capped gold nanoclusters as a fluorescent probe for specific detection of folic acid via a ratiometric fluorescence strategy

“…[1][2][3][4] FA is involved in the formation of red blood cells, as well as the acquisition, transport and enzymatic processing of one carbon unit for amino acid and nucleic acid metabolism. 5,6 Meanwhile, many reports have demonstrated that FA and vitamin B 12 play essential roles in the synthesis of DNA and RNA. 7 The lack of FA gives rise to gigantocytic anemia, leukopenia, mental health issues, psychosis and other diseases.…”

Simple and sensitive detection method for diprophylline using glutathione-capped CdTe quantum dots as fluorescence probes

“…Fig. 1B shows that the line width of the fluorescence spectrum is narrow, which shows that the as-prepared CdTe QDs were nearly monodisperse and homogenous [32]. The fluorescence intensity shows a rising tendency with refluxing time from 1 h to 3 h, followed by a significant decrease when the refluxing time was further increased to 6 h. The maximum fluorescence intensity was observed at a reflux time of 3 h. This result indicates that the QDs gradually grew at a controlled speed.…”

A “turn-on” fluorescent receptor for detecting tyrosine phosphopeptide using the surface imprinting procedure and the epitope approach

“…The phosphate anion group of pTyr might conjugate with the Cd (II) in the surface of CdTe QDs and the coordination of phosphate group of pTyr leads to the adsorption of pTyr onto the surface of CdTe semiconducting particles and such decrease the surface defects (Ojida et al, 2002;Ojida et al, 2004;Wang et al, 2009).
