The development of smart nanoparticles that enable to circumvent biological barriers and transport cargoes to target sites in the body promises safer and more effective drug delivery. Since cell membrane-based nanovesicles have the characteristics of both nano-sized and cell-based drug delivery platforms, they are regarded as promising cancer targeted delivery tools for both endogenous and exogenous cargos. What is perhaps most fascinating about these cell membrane-based drug delivery systems is that the natural targeting ability of those producing cells makes the exogenous engineering of targeting moieties unnecessary. In our laboratory, a variety of bio-inspired nano-biomaterials, such as virus-like nanoparticles and ferritin nanocages, have been studied for drug delivery, cell labeling, and gene therapy. A number of hybrid nanoparticles containing synthetic and biological components have been utilized for achieving sustained release and target-specific delivery. We are particularly interested in cell membrane-based nanoparticles containing bioactive molecules useful for therapeutic and imaging applications in cancer theranostics. In this presentation, an innovative biomimetic nanoparticle platform for delivering therapeutic anticancer agents and imaging-guided cancer therapy will be introduced. In addition, the major hurdles in the clinical translation of cell membrane-based delivery systems will be discussed.
