Aqueous phase synthesis of CdTe quantum dots for biophotonics [PDF]
Journal of Biophotonics, 2010 AbstractOver the past few years, CdTe quantum dots have been demonstrated as powerful probes for biophotonics applications. The aqueous phase synthesis technique remains the best approach to make high quality CdTe QDs in a single‐pot process. CdTe QDs prepared directly in the aqueous phase can have quantum yield as high as 80%. In addition, the surface

Interaction of CdTe quantum dots with DNA
Electrochemistry Communications, 2008 Abstract The interaction between dsDNA and CdTe QDs was investigated by an indirect electrochemical method with the assistance of electroactive dsDNA indicator Co ( phen ) 3 3 + / 2 (phen = 1,10-phenanthroline). The results indicated that CdTe QDs had an obvious effect on Co ( phen ) 3 3 + / 2 + /dsDNA ...

Bacterial phototoxicity of biomimetic CdTe‐GSH quantum dots
Journal of Applied Microbiology, 2020 Fluorescent semiconductor nanoparticles or quantum dots (QDs) have excellent properties as photosensitizers in photodynamic therapy. This is mainly a consequence of their nanometric size and the generation of light-activated redox species. In previous works, we have reported the low-cost biomimetic synthesis of glutathione (GSH) capped QDs (CdTe-GSH ...

Probing the interactions of CdTe quantum dots with pseudorabies virus [PDF]
Scientific Reports, 2015 AbstractQuantum dots (QDs) have become one of the most promising luminescent materials for tracking viral infection in living cells. However, several issues regarding how QDs interact with the virus remain unresolved. Herein, the effects of Glutathione (GSH) capped CdTe QDs on virus were investigated by using pseudorabies virus (PRV) as a model.

Fe doped CdTeS magnetic quantum dots for bioimaging [PDF]
Journal of Materials Chemistry B, 2013 A facile synthesis of 3-6 nm, water dispersible, near-infrared (NIR) emitting, quantum dots (QDs) magnetically doped with Fe is presented. Doping of alloyed CdTeS nanocrystals with Fe was achieved in situ using a simple hydrothermal method. The magnetic quantum dots (MQDs) were capped with NAcetyl-Cysteine (NAC) ligands, containing thiol and carboxylic
