Abstract

Metal organic frameworks (MOFs) are a unique class of smart hybrid materials that have recently attracted significant interest for catalysis, separation and biomedical applications. Different strategies have been developed to overcome the limitations of MOFs for bio-applications in order to produce a system with high biocompatibility and biodegradability. In this review, we outline the chemical and physical factors that dictate the biocompatibility and biodegradability characteristics of MOFs including the nature of the metal ions and organic ligands, size, surface properties and colloidal stability. This review includes the in-vitro biodegradation and in-vivo biodistribution studies of MOFs to better understand their pharmacokinetics, organs toxicity and immune response. Such studies can guide the design of future bio-friendly systems that bring us closer to safely translate these platforms to the pharmaceutical consumer market.
