Study of the interaction between CdSe/ZnS core-shell quantum dots and bovine serum albumin by spectroscopic techniques

Probing the interaction of flower-like CdSe nanostructure particles targeted to bovine serum albumin using spectroscopic techniques

“…Given the potential applications of CdSe in labels and probes, it is important to evaluate its influence on biomolecules. Though the interaction of CdSe QDs with biomolecules has been already studied clearly [23][24][25], there were few studies about the interaction of other morphologies of CdSe NP with BSA. Therefore, the influence of flower-like CdSe nanostructure particles on protein in real cells can be simulated in this study choosing BSA as a model.…”

BSA‐conjugated zinc oxide nanoparticles as luminescent probes for the determination of histidine

“…Based on the value of K SV and the dimolecular quenching equation, K q was calculated to be 3.30 × 10 13 L/mol/s. Obviously, the calculated quenching constant is greater than the maximum diffusion collision quenching constant (2.0× 10 10 L/mol/s) due to the collision mechanism , implying that the quenching is not initiated by dynamic collision, but results from static quenching .…”

“…Based on the value of K SV and the dimolecular quenching equation, K q was calculated to be 3.30 × 10 13 L/mol/s. Obviously, the calculated quenching constant is greater than the maximum diffusion collision quenching constant (2.0× 10 10 L/ mol/s) due to the collision mechanism (31), implying that the quenching is not initiated by dynamic collision, but results from static quenching (32). In order to collect additional evidence for the quenching mechanism of BSA@ZnO nanoparticles by His, the quenching efficiency of BSA@ZnO nanoparticles at different temperatures was investigated ( Fig.…”

Synthesis and characterization of aspartic acid-capped CdS/ZnS quantum dots in reverse micelles and its application to Hg(II) determination

“…Frequently, this modification gives rise to obtain high significant luminescent QDs. In addition, attachment of organic ligands to their surface can provide high selectivity for many specific applications [16][17][18][19][20][21].…”
