PAMAM dendrimer, ethylenediamine core, generation 4.0 solution, is widely used in drug delivery systems due to its well-defined structure and ability to encapsulate or conjugate therapeutic agents. Its highly branched architecture allows for efficient loading of drugs, enhancing targeted delivery and reducing side effects. In gene therapy, it serves as a non-viral vector for DNA and RNA delivery, facilitating cellular uptake and transfection. Additionally, it is employed in diagnostic imaging as a carrier for contrast agents, improving imaging resolution. The dendrimer is also utilized in catalysis, where its surface functional groups can be tailored to support specific catalytic reactions. In materials science, it is incorporated into coatings and nanocomposites to enhance properties like stability and functionality. Its versatility makes it a valuable tool in biomedical research, nanotechnology, and industrial applications.
