There are several types of smart delivery systems, including:
Liposomes: Spherical vesicles composed of lipid bilayers, commonly used to deliver anticancer drugs. Polymeric nanoparticles: These are made from biocompatible polymers and can be engineered for controlled release profiles. Dendrimers: Branched, tree-like structures with cavities that can hold drug molecules. Gold nanoparticles: Used for their stability and ease of functionalization, often in imaging and photothermal therapy. Silica nanoparticles: Known for their porous structure, allowing for high drug loading capacity.
