There have been many recent exciting developments in biomimetic nanoparticles for biomedical applications.Inflammation,a protective response involving immune cells,blood vessels,and molecular mediators directed against harmful stimuli,is closely associated with many human diseases.As a result,biomimetic nanoparticles mimicking immune cells can help achieve molecular imaging and precise drug delivery to these inflammatory sites.This review is focused on inflammation-targeting biomimetic nanoparticles and will provide an in-depth look at the design of these nanoparticles to maximize their benefits for disease diagnosis and treatment.
