We have developed a glucose-responsive metal-organic framework (MOF)-based insulin delivery nanosystem via a one-pot process. The system relies on the MOF response to glucose stimulation and this can promote insulin delivery. This nanosystem was successfully applied for glucose-responsive and self-regulated insulin release.
A label-free nanozyme MIL-53(Fe) with the dual-function of catalyzing and emitting fluorescence was utilized for turn-on fluorescence detection of hydrogen peroxide and glucose. The proposed strategy provides a cost-effective, safe and sensitive method for the design and development of multiple enzyme cascade assays for various biomolecules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
