Colloque
Dye-doped silica nanoparticles (NPs) and semiconductor nanocrystals, i.e. quantum dots (QDs), offer great potential as a new generation of biomarkers for highly sensitive detection down to single-molecule level. Herein, we present our work on the controlled synthesis of these two types of NPs. I will also briefly talk about the development of multifunctional NPs that integrate photoluminescence and superparamagnetism into a single nano-architecture. Several types of dyes, which have varying molecular weights and are capable of forming different bonding with silica networks, have been exploited to form dye-doped silica NPs. It is found that these dyes show quite different photophysical …
