Bifunctional nanocapsules for magnetic resonance imaging and photodynamic therapy†
Abstract
Here we present the fabrication of bifunctional nanocapsules via cation (Ca2+/Gd3+) induced self-assembly of partially hydrolysed α-lactalbumin. The prepared nanospheres, encapsulated with photosensitizer (Rose Bengal) and Gd3+ ion, show great potentials for magnetic resonance imaging and photodynamic therapy with a target-specific manner.
