PAMAM dendrimers with an ethylenediamine core are widely used in drug delivery systems due to their well-defined structure and ability to encapsulate or conjugate therapeutic agents. They enhance the solubility and stability of drugs, allowing for targeted delivery and controlled release, particularly in cancer therapy. These dendrimers are also employed in gene delivery, where they facilitate the transport of genetic material into cells, improving the efficiency of gene therapy. In diagnostics, they serve as carriers for imaging agents, enhancing contrast in techniques like MRI. Additionally, PAMAM dendrimers are utilized in industrial applications, such as catalysis and nanotechnology, where their high surface area and functional groups enable precise modifications and efficient reactions.
