Recent progress in drug delivery and cancer theranostic built from metal-organic frameworks.

With the improvement of living standards, cancer has become a great challenge around the world during last decades, meanwhile, abundant nanomaterials have been developed as drug delivery system (DDS) or cancer theranostic agents (CTA) with their outstanding properties. However, low multifunctional efficiency and time-consuming synthesis limit their further applications. Nowadays, green chemistry, in particular, the concept of atom economy, has defined new criteria for the simplicity and efficient production of biomaterials for nanomedicine, which not only owns the property of spatio-temporal precision imaging, but also possess the ability to treat cancer. Interestingly, metal-organic framework (MOF) is an excellent example to meet the requirements behind this concept and has great potential for next-generation nanomedicine. In this review, we summarize our recent researches and inspiring progresses in designing DDS and CTA built from MOF, aiming to show the simplicity, control, and versatility, and provide views on the development of MOF-based nanomedicine in the future.
