Experts Review:

Dr. Ms. Kamiko Chang, Ph.D(University of Science and Technology Beijing, China)
Quantum Dot Biolabeling are nano sized semiconductor particles having their size reduced in all three dimensions; as size reduces the diameter of the particle approaches the exciton Bohr diameter and the charge carriers become confined in three dimensions. This phenomenon is known as quantum confinement, causes the continuous band of the bulk to split into discrete, quantized levels.

Quantum Dot Biolabeling provides an important tool for the investigation of basic physical properties of biological structures. The high sensitivity of fluorescence, combined with the advances in measurement techniques, allows the detection of ultra small quantities of specific species present in biological systems. The fluorescence process one of the known luminescence phenomena in which susceptible molecules or aggregates emit light from electronically excited states created by either a physical.

The use of Quantum Dot Biolabeling as probes for bioanalytical applications is a highly promising technique because fluorescence-based techniques are very sensitive. Quantum dots (QDs) seem to show the greatest promise as labels for tagging and imaging in biological systems owing to their impressive photostability, which allow long-term observations of biomolecules. The usage of Quantum Dot Biolabeling in practical applications has started only recently, therefore, the research on QDs is extremely important in order to provide safe and effective biosensing materials for medicine.

Quantum Dot Biolabeling can be used in different ways to detect analytes. As active sensor elements the fluorescence properties of the QDs are changed upon reaction with the analyte. Fundamental studies have revealed that chemical or physical interactions between a given chemical species (the analyte) with the particle surface can result in changes in the QDs

Dr. Darren Chandler, Ph.D(Manchester Metropolitan University, U.K)
Quantum Dot Biolabeling have some unique photophysical properties. They have a continuous absorption spectrum for wavelengths shorter than the wavelength of fluorescence emission. Their emission spectra are quite narrow and symmetric, and do not show any red-tail. In this way many different colors can be excited with just one wavelength of excitation and can be spectrally well resolved. The fluorescence lifetime is a few ns and thus is significantly higher than that of organic fluorophores.
