A new class of fluorescent labels has been produced by conjugating water soluble quantum dots (QDs) with biomolecules. Quantum Dots (QDs) are semiconductor nanocrystals (1~10 nm) exhibiting distinctive photoluminescence (PL) properties due to the quantum confinement effect. The resultant nanoprobes can potentially overcome many of the functional limitations encountered with organic dyes. High-quality quantum dots are highly stable against photobleaching and have narrow, symmetric emission spectra. In particular, the emission wavelength of quantum dots can be continuously tuned by simply…mehr

Produktbeschreibung
A new class of fluorescent labels has been produced by conjugating water soluble quantum dots (QDs) with biomolecules. Quantum Dots (QDs) are semiconductor nanocrystals (1~10 nm) exhibiting distinctive photoluminescence (PL) properties due to the quantum confinement effect. The resultant nanoprobes can potentially overcome many of the functional limitations encountered with organic dyes. High-quality quantum dots are highly stable against photobleaching and have narrow, symmetric emission spectra. In particular, the emission wavelength of quantum dots can be continuously tuned by simply changing the particle size, and a single light source can be used for simultaneously excitation of all different-colored dots. These novel optical properties can render quantum dots ideal fluorophores for sensitive, Multicolor and multiplexing applications in molecular biology and bioengineering.
Autorenporträt
Nanotechnology is the manipulation and rearranging of matter on an atomic and molecular scale to create useful materials, devices & systems. The term "nano-technology" had been coined by Norio Taniguchi in 1974. D. K. Gupta (M.Tech) and Dr. N.D. Jasuja (M.Sc., Ph.D), both are Assistant Professor in Jayoti Vidyapeeth Women University, Jaipur,India.
