Bright, non-blinking, and less-cytotoxic SiO2 beads with multiple CdSe/ZnS nanocrystals.


A method including surface silanization, phase transfer and self-assembly, and SiO2 shell growth has been developed to incorporate multiple hydrophobic CdSe/ZnS nanocrystals into SiO2 beads where they are well suited for bio-application due to their high brightness, less-cytotoxic, and non-blinking nature.
