Cy5 dye is widely used as a biomarker in the research fields of life science because of its excitation at wavelengths above 600nm where autofluorescence of bio-matter is much reduced. However, Cy5 dye could not be encapsulate into silica directly to form stable nanoparticles by using of the traditional methods. In this paper, an improved method had been developed to prepare Cy5 dye doped core-shell...
Here some progresses of core-shell nanoparticles (NPs) for biomedical applications have been reported. A new synthesis mechanism for preparation of core-shell NPs by using water-in-oil (W/O) microemulsion technique has been investigated. And the applications of the core-shell NPs on cell recognition, oligonucleotide detection, single bacterial detection, pH nano-sensor for single cell, DNA recovery...
Based on the reverse microemulsion technique, luminescent quantum dots doped core-shell nanoparticles have been prepared by employing silica as the shell and CdTe quantum dots as the core of the nanoparticles, which have an excellent solubility and dispersibility, especially amine and phosphonate groups have been modified on their surface synchronously. In comparison with CdTe quantum dots, these...
