Understanding the stability of zeolitic imidazolate framework-8 (ZIF-8) under physiological conditions is critical in biotechnology and biomedicine for biosensing, biocatalysis, drug delivery.
Metal–organic frameworks (MOFs) combined with biomacromolecules, viruses and cells have emerged as novel biocomposites for application to drug delivery, biosensing, biospecimen preservation, cell virus manipulation.
