Dendrimers are highly branched, three-dimensional polymers that show promise in drug delivery applications. They can be precisely engineered with specific properties. Dendrimers can encapsulate or conjugate to drugs and release them in a controlled manner over time. They offer advantages over other delivery systems like liposomes due to their well-defined structure and multivalent surface. Current research is exploring dendrimers for targeted delivery of anticancer drugs, gene therapy, and other pharmaceutical uses to improve treatment outcomes.
