Here we critically examine whether coating of nanoparticles with platelet membranes can truly disguise them against recognition by elements of the innate immune system. We further assess whether the "cloaking technology" can sufficiently equip nanoparticles with platelet-mimicking functionalities to include in vivo targeting of damaged blood vessels and binding to platelet-adhering opportunistic pathogens. We present views for improved, and pharmaceutically viable nanoparticle design strategies.
