As a cornerstone of synthetic chemistry, the coordination of organic ligands to
ions/clusters has been used to prepare many types of materials, including metal
complexes, metal–organic polyhedral, porous coordination polymers, porous
coordination networks, and metal–organic frameworks (MOFs) [1]. These
metal–organic materials are assembled by metal coordination, hydrogen bonding,
electrostatic interactions or – stacking [2], exhibiting tunable structures,
compositions and properties. Therefore, they are considered as promising candidates
in the fields of catalysis, gas adsorption and separation, sensors, functional devices,
etc [3]. Notably, biomedical applications have greatly benefited from the progress
made by these metal–organic materials in the fields of diagnosis, monitoring, and
therapy. Some of the biomedical applications of metal–organic materials include
biosensors, biocatalysis, bioimaging, drug delivery, anticancer, antibacterial, and
wound healing. This part mainly focuses on different types of metal complexes and
MOFs for biomedical applications, specifically, for antibacterial and biosensing
applications
