Oil soluble CdSe/ZnS quantum dots administered

 (1) a wide range of excitation wavelength, emission wavelength range is narrow, can use the same kind of excitation light and stimulate a variety of quantum dots, emit fluorescence at different wavelengths. Compared with the traditional fluorescent dye molecules, fluorescent dye excitation wavelength range is narrow, the needs of a variety of wavelength of the excitation light to stimulate a variety of fluorescent dye, brought a lot of inconvenience to the practical work.

 (2) the narrow and symmetric emission peak, overlap was low, and the fluorescent dye emission peak width and asymmetry, trailing only, serious, serious overlapping each other, easy to interfere with each other, bring the problem to solve for analysis and detection.

 (3) the emission wavelength can be controlled by the size and the composition of tuning, can any desired wavelength quantum dots synthesis, quantum dot size uniform spectral peak for the symmetric Gauss distribution.

 (4) the fluorescence intensity and stability is about 100 times of the ordinary fluorescent dye, can be observed for a long time after the labeled objects.

 (5) through the quantum point after various chemical modification, good biocompatibility, can be connected to the organism specific, small damage, can be in vivo labeling and detection of fluorescent dye, and general toxicity, poor biocompatibility.

 My company has the quantum dot sound R & D team, the use of advanced production technology is different from the past, quantum dots for the production of the emission spectrum from blue to near infrared precision adjustable, high chemical stability and optical stability good, quality stability, high quantum yield, and can provide different specifications, different concentrations of water the water-soluble and oil soluble quantum dots, can also according to customer requirements for the specific function of the.
