Abstract

Biomimetic nanotechnology could serve as an advancement in the domain of drug delivery and diagnosis with the application of natural cell membrane or synthetically-derived membrane nanoparticles (NPs). These biomimetic NPs endow significant therapeutic and diagnostic efficacy by their unique properties, such as immune invasion and better targeting ability. Additionally, these NPs have a unique ability to retain the inherent properties of cell membrane and membrane's intrinsic functionalities, which helps them to exhibit superior therapeutic effects. In this review, we describe how these membrane-clocked NPs endow superior therapeutic effects by immune invasion; along with this, the development of membrane-coated NPs and their method of preparation and characterization has been clearly described in the manuscript. Moreover, Various developed membrane-coated NPs such as red blood cell membrane-coated NPs, white blood cells membrane-coated NPs, platelet membrane coated, cancer cell membrane coated, bacterial membrane vesicles and, mesenchymal stem cells membrane-coated NPs have been established in this manuscript. At last, the discussion on the role of membrane-coated NPs as theranostics, and notably, the literature that demonstrates the shreds of evidences of these NPs in targeting and neutralizing the SARS-CoV-2 virus have also been incorporated.
