Semiconductor nanocrystal quantum dots with their tunable optical properties, narrow photoluminescence, and high photostability have generated great interest in light-emitting device applications. [1, 2] Such colloidal quantum dots that are directly electrically driven in light-emitting diode (LED) structures have been extensively studied in the last decade. However, these LEDs unfortunately suffer...
Quantum dots (QDs) have attracted tremendous interest in biological applications, such as bioimaging, biolabeling, and biosensing, because of their advantages over organic fluorophores at high quantum yield (QY), size-tunable narrow emission, photostability, etc. To date, various strategies have been developed to obtain water-soluble QDs and QD bioconjugates, but these commonly require multiple steps...
The development of high-sensitivity and specificity probes that lack the intrinsic limitation of organic fluorescent dyes and sensitizers is of considerable interest in many areas of research, from cellular biology to molecular imaging and diagnostics. Quantum dots (QDs) are stable, bright fluorophores that can give high quantum yields, narrow emission bands, intense absorbance, very large Stokes...
Due to the low photostability of conventional organic fluorophores, their effectiveness in detecting proteins in highly autofluorescent cyanobacterial cells is limited. However, the inorganic fluorescent nanocrystal (Quantum Dot or Qdot) conjugates have the capability to overcome the limitation of organic fluorophores, and provide a promising tool for long-term imaging studies. In this study, we applied...
