Synthesis of CdTe Quantum Dots in Aqueous Solution and Their Optical and Structural Characterization

A simple and sensitive label‐free fluorescence sensing of heparin based on Cdte quantum dots

“…Glutathione‐capped CdTe QDs also have higher quantum yields (QYs) than the CdTe QDs capped with other thiol compounds, without any post‐preparative treatment. These values were comparable with, or even better than, most QDs prepared because of a better surface access of the CdTe crystalline lattice by glutathione (24‐26). The unique advantages of this method are its very fast process, its low cost, and its ease of production and the high sensitivity switch in methods for heparin sensing in human serum samples.…”

Supercritical CO2-assisted synthesis of an ultrasensitive amphibious quantum dot-molecularly imprinted sensor

“…The NMR spectra were recorded on a Bruker ARX 400 MHz equipment using CDCl 3 as solvent. 1 H and 13 C NMR chemical shis are reported as d (ppm ¼ parts per million) relative to the residual solvent peak. The UV-spectra were acquired in a Perkin-Elmer Lambda 25 UV-Vis Spectrometer with a slit width of 5 nm.…”

“…In comparison to conventional probes, QDs oen exhibit superior optical and electronic properties, such as strongly size-dependent high photoluminescence, great photostability, broad excitation spectrum and highly stable photobleaching. 1 In order to improve the selectivity of QD-based sensors, its incorporation into molecularly imprinted systems emerges as an effective technique. Molecularly imprinted polymers (MIPs) are produced by the copolymerization of selected monomers and cross-linkers, in the presence of a template (target) molecule, thus producing polymer networks with cavities that have complementary size, shape and functionality of the target molecule, leading to materials with high specicity and selectivity.…”

An investigation on the structural and optical properties of MSA capped CdTe quantum dots

“…Over the recent years, CdTe QDs have received remarkable research attention because of their tunable band gap, high fluorescence efficiency, and high quantum yield [1,2,10]. They can be made to show tunable photoluminescent properties in the visible spectrum (~ 500-750 nm) by controlling their particle size [11,12]. Moreover, a single excitation wavelength of light can simultaneously excite all colours of CdTe QDs [1,11,13].…”
