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. Their high surface functionality allows for targeted delivery, enhancing the efficacy of drugs while minimizing side effects. In gene therapy, these dendrimers serve as non-viral vectors for DNA and RNA delivery, facilitating transfection into cells. They are also employed in diagnostic imaging as contrast agents, improving the resolution of imaging techniques. Additionally, their use in catalysis is notable, as they provide a platform for immobilizing catalysts, enhancing reaction efficiency. In materials science, PAMAM dendrimers are utilized to create nanostructured materials with tailored properties for various industrial applications.
