PAMAM dendrimer, ethylenediamine core, generation 2.5 solution, is widely used in drug delivery systems due to its highly branched structure and ability to encapsulate or bind therapeutic agents. Its surface functional groups allow for targeted delivery, improving the efficiency of treatments while minimizing side effects. In gene therapy, it serves as a non-viral vector for DNA and RNA delivery, facilitating the transfer of genetic material into cells. Additionally, it is employed in diagnostic imaging as a contrast agent carrier, enhancing the visibility of tissues or organs in medical scans. Its application also extends to catalysis, where it acts as a nanoreactor or support for catalytic molecules, enabling efficient chemical reactions. In material science, it is utilized to create nanocomposites, improving the mechanical and thermal properties of polymers.
