Abstract: Metal-organic frameworks (MOFs) are porous crystalline polymers constructed from the coordination reaction between organic ligands and metal ions. Due to their advantages:adjustable periodic pore structure, large specific surface area and easy functional modification, etc., MOFs have been widely used in the fields of gas storage/separation, catalysis, sensing, biological imaging and drug delivery. In recent years, MOFs have shown great potential in disease diagnosis and treatment. This review summarizes the application of MOFs in the fields of bio-sensing, cell imaging, in vivo imaging, drug delivery, etc., discusses the problems and corresponding solutions in the application of MOFs for biomedicine. We hope this review can provide reference for the designing new methods for disease diagnosis and treatment.
