Nanoparticles embedment of protein

Cell membranes, consisting of lipid bilayers with embedded proteins, separate interior and exterior of cells and are selectively permeable to protect the intracellular environment. The Upid bilayer typically permits diffusion of small and non-polar molecules while preventing diffusion of polar and large molecules. Most of the nanoscale macromolecules are not able to freely diffuse across the cell membranes but can be engineered to internalize into cells through various mechanisms upon contact with the cell membrane. Critical to their use in biomedical applications, the interaction of nanoparticles with cell membranes is...
