Design and degradation of permanently porous vitamin C and zinc-based metal-organic framework - Communications Chemistry
Metal–organic frameworks have demonstrated great potential as drug delivery systems, but the biocompatibility of the MOF components is often overlooked. Here, a vitamin C and zinc-based MOF with permanent microporosity is designed, and successful loading and release of model drug urea from the MOF pores, as well as degradation of the framework, are demonstrated.
