Experts Review:

Dr. Ms. Kamiko Chang, Ph.D(University of Science and Technology Beijing, China)
Quantum Dot DNA Conjugation represent a revolution in the application of fluorophores for biological labeling when compared to traditional dye labels, because they are photo and chemically stable and have high quantum yield. In addition, different fluorescence wavelengths, i.e., colors, can be achieved by simply varying the QD size; and all colors of QDs can be excited by a single excitation source, which makes it much easier to excite QDs than traditional fluorescent dyes that possess relatively narrow absorption bands.

We have developed the method for the Quantum Dot DNA Conjugation to streptavidin-coated quantum dots (QDs). Quantum Dot DNA Conjugation and a highly sensitive fluorescence imaging technique are adopted to visualize gene transport across the membrane of the live cell in real time.

Fluorescent semiconductor nanocrystals, Quantum Dot DNA Conjugation have significant advantages over the classical organic dyes with their unique properties and they are expanding application fields in life sciences. DNA labeling by conjugation of QDs to DNA is the first step for studying kinetics of DNA transfer from the extracellular to the intracellular space through live cell imaging techniques.

We have developed an inorganic/organic hybrid Quantum Dot DNA Conjugation that produces an extremely low level of background fluorescence, difficult to achieve with conventional organic Quantum Dot DNA Conjugation. Each DNA nanosensor consists of two target-specific oligonucleotide probes, which include a reporter probe labelled with a fluorophore and a capture probe labelled with biotin.

We have synthesized very compact Quantum Dot DNA Conjugation probes where the density of the probes on the QD surface was controlled avoid steric hindrance. The size of the functionalized QD was approximately 3 nm, which is the closest possible distance between the donor and the acceptor. Using the QDs developed in this work, the DNA detection could be completed in 10 min with a sub-nM detection limit. Our Quantum Dot DNA Conjugation probes can be used in the development of highly sensitive and specific sensors for applications in biomedical, homeland security, and life sciences.
