WebThe disadvantage of PEG is that it sometimes reduces the interaction between target cells and the nanoparticles. Entry of nanoparticles into the brain is restricted by the blood brain barrier. One of the major pathways of entry of these particles into the brain is through endocytosis by the endothelial cells of capillaries in the brain. WebPEG (Figure 7.6) is a biocompatible and hydrophilic material, with properties that limit antigenicity, immunogenicity, cell adhesion, and protein binding (Alcantar, Aydil, & … hotel at climping west sussex
