There are several types of smart drug delivery systems, each with unique mechanisms and advantages:
Liposomes: These are spherical vesicles that can encapsulate drugs, protecting them from degradation and enhancing their delivery to cancer cells. Polymeric Micelles: These are self-assembling structures that can carry hydrophobic drugs, increasing their solubility and stability. Dendrimers: These are branched molecules with a high degree of surface functionality, allowing for the attachment of multiple drugs or targeting agents. Nanoparticles: These can be engineered from various materials and can be designed to release drugs in response to specific triggers.
