Abstract:
Light on target : Silica‐coated upconverting nanophosphor (UCNP) nanocomposites have been synthesized with organic dye (fluorescein isothiocyanate, FITC) incorporated in the silica shell. The nanocomposites are well dispersed and have good photostability and biocompatibility. These nanocomposites readily conjugated with folic acid for targeted multimodal bioimaging (see schematic representation).
