When nanoparticles (NPs) enter a physiological environment, a complex coating of biomolecules is absorbed onto their surface, known as the biocorona (BC). This coating alters nanomaterial physical properties, modulating cellular viability, internalization, and immune responses. To safely utilize NPs within medical settings, it is necessary to understand the influence of the BC on cellular responses. Due to the variety of cell types, NPs, and physiological environments, responses are variable; though trends do exist. This review article critically evaluates the currently available literature regarding the influence of the BC on NP interactions with prominent cell types that they are likely to encounter during biomedical applications. Specifically, we will examine responses related to interactions with endothelial cells, macrophages, and epithelial cells of the digestive tract and lung. Further, we will evaluate how the BC may influence interactions with bacteria and fungi, as NPs have been proposed as antimicrobial agents in medical settings. The information reviewed and discussed here may enhance the development of effective of NP‐based therapeutics and diagnostic tools.
