Under the optimum conditions, a limit of detection as low as 8.5 × 10-8 M was obtained using GSH-CdTe@ZnS. The effects of foreign reactive oxygen species and the Fenton reactants and products as possible interferences on the proposed probe were negligible for CdTe@ZnS QDs. Besides, experimental results indicated that CdTe@ZnS QDs were more attractive for the selective recognition of ●OH than CdTe QDs. The mechanistic reaction pathway between the QDs and ●OH is proposed.]]> Tue 17 May 2022 14:45:18 SAST ]]> Synthesis and characterization of quantum dots designed for biomedical use https://vital.seals.ac.za/vital/access/manager/Repository/vital:7310 Thu 13 May 2021 06:18:14 SAST ]]> The design of quantum dots and their conjugates as luminescent probes for analyte sensing https://vital.seals.ac.za/vital/access/manager/Repository/vital:4457 Thu 13 May 2021 03:30:35 SAST ]]> Probing the sensitive and selective luminescent detection of peroxynitrite using thiol-capped CdTe and CdTe@ ZnS quantum dots https://vital.seals.ac.za/vital/access/manager/Repository/vital:45393 GSH–TGA–CdTe@ZnS>MPA–CdTe QDs. The varying degree of quenching is elucidated based on the QD–thiolate bond of CdTe@ZnS being more sensitive to oxidation from ONOO− than CdTe. The selectivity of the probe in the presence of co-existing species followed the order: GSH–TGA–CdTe@ZnS>MPA–TGA–CdTe@ZnS>MPA–CdTe QDs. QDs capped with MPA showed less selectivity for ONOO− than GSH. The best limit of detection (LOD) of 12.6 nM was obtained for MPA–TGA–CdTe@ZnS QDs. Time-resolved fluorescence measurements indicated that the interaction between ONOO− and the QDs is static in nature.]]> Sat 27 Nov 2021 14:07:54 SAST ]]> Photophysical properties of a series of alloyed and non-alloyed water-soluble l-cysteine-capped core quantum dots https://vital.seals.ac.za/vital/access/manager/Repository/vital:44758 Sat 04 Dec 2021 12:16:50 SAST ]]> CdTe quantum dots functionalized with 4-amino-2, 2, 6, 6-tetramethylpiperidine-N-oxide as luminescent nanoprobe for the sensitive recognition of bromide ion https://vital.seals.ac.za/vital/access/manager/Repository/vital:51253 Fri 20 May 2022 23:08:42 SAST ]]>
