Abstract
Up to the neck! Bio-safe upconversion fluorescent nanocrystals (NaYF 4:ErYb) and biocompatible superparamagnetic iron oxide nanocrystals (SPION) were effectively combined by means of a general "neck- formation" strategy forming a size-controlled Cd2+- and Gd 3+-free silica-shielded magnetic upconversion fluorescent oligomer (SMUFO) bimodal cancer probe that offers high resistance to photoquenching as well as a synergistic T2-weighted magnetic resonance enhanced effect (see graphic).
