Metal-Organic-Framework-Derived Mesoporous Carbon Nanospheres Containing Porphyrin-Like Metal Centers for Conformal Phototherapy

摘要

Mesoporous carbon nanospheres containing porphyrin-like metal centers (denoted as "PMCS") are successfully synthesized by the pyrolysis of an imidazolate framework using a mesoporous-silica protection strategy. The PMCS allow infrared and photoacoustic imaging and synergetic photothermal therapy/photodynamic therapy derived from the porphyrin-like moieties, offering the possibility of real-time monitoring of therapeutic processes and image-guided precise conformal phototherapy. PMCS thus represent a novel multifunctional theranostic platform for improved treatment efficiencies.
