Nanoparticle behaviours in different biological media

Formation of protein corona on the surface of nanoparticles has plenty of implications that would affect its cellular responses and thus changing its type of application. Inorganic nanoparticles hold great promise in food, cosmetic and biomedical applications. Studying the formation of corona on dif...
