Figure 4. The main classifications of nanopolymers are divided into two categories based on their organic and inorganic properties; inorganic NPs are mainly named based on their compounds, such as silicon NPs, iodine oxides NPs, and so on, while organic NPs can be divided into many categories. In this article, organic NPs are classified into two categories: Polymeric and Lipid-based. Polymeric mainly includes Polymersome, Dendrimer, Micelle, and Nanoball. For Lipid-based, they mainly include liposomes, lipids, nanoparticles, emulsions, etc.
