PAMAM-OH dendrimer, generation 3 solution, is widely used in drug delivery systems due to its well-defined structure and ability to encapsulate or bind therapeutic agents. Its dendritic architecture allows for efficient transport of drugs, enhancing targeted delivery and reducing side effects. In gene therapy, it serves as a non-viral vector for delivering nucleic acids, facilitating cellular uptake and transfection. Additionally, it is employed in diagnostic imaging as a contrast agent carrier, improving imaging precision. The material is also utilized in catalysis, where its surface functional groups can stabilize and enhance the activity of catalytic nanoparticles. In environmental applications, it aids in the removal of pollutants through adsorption or degradation processes. In the cosmetics industry, it is used as an ingredient in skin care products, enabling better penetration of active substances into deeper skin layers, thereby enhancing product efficacy. Its biocompatibility and versatility make it valuable in biomedical research and industrial applications.
