A novel type of Rubpy-doped fluorescent nano-particles has been prepared using a water-in-oil(W/O) microemulsion method. Characterizations by transmission electron microscopy, fluorescent spectra, photostability experiments and dyeleaking experiments show that the nanoparticles are spherical, monodisperse, and uniform in sharp and size (70 ± 5nm). Due to a lot of fluorescent dye molecules encapsulated...
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...
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...
Fluorescent nanocrystal quantum dots (QDs) are widely used as novel tools in various biological fields including cellular biology, molecular biology, and even in basic and clinical medical fields, due to their far brighter photoemission and photostability. Although many amounts of biological studies, including in vivo experiments, were circumstantially investigated, there is no informative report...
