Biomolecular Corona Affects Controlled Release of Drug Payloads from Nanocarriers

Abstract

Nanomedicine has been widely used for a wide range of biomedical applications including drug delivery. Although many factors including the physicochemical properties of nanoparticles (NPs) and the payload efficacy of nanocarriers have been thoroughly investigated, the crucial role of the biomolecular corona in drug delivery and the release efficacy of nanocarriers demands further attention. This review highlights not only the crucial importance of the biomolecular corona to the drug release capacity of various types of nanocarriers, but also its interference with drug release measurements. A full consideration of the effects of the biomolecular corona on the controlled release and drug delivery of nanocarriers will help researchers design safer and more efficient nanobased drug delivery systems.
