Drug Delivery: Up-Conversion Luminescent and Porous NaYF₄:Yb³⁺, Er³⁺@SiO₂ Nanocomposite Fibers for Anti-Cancer Drug Delivery and Cell Imaging (Adv. Funct. Mater. 13/2012)

Up-conversion luminescent and porous NaYF₄:Yb³⁺, Er³⁺@SiO₂ nanocomposite fibers are prepared via an electrospinning process. As reported by Ping'an Ma, Jun Lin, and co-workers on page 2713, the fibers can be used as anticancer drug delivery host carriers and the drug release shows sustained, pH-sensitive release patterns. The fiber fragments loaded with drug show near-infrared up-conversion emission and this can be applied in the field of cell imaging.
