PAMAM dendrimer, ethylenediamine core, generation 4.5 solution, is widely used in drug delivery systems due to its unique dendritic structure, which allows for efficient encapsulation and controlled release of therapeutic agents. Its high surface functionality enables conjugation with various drugs, targeting ligands, and imaging agents, making it valuable in targeted cancer therapy and diagnostic applications. Additionally, it serves as a gene delivery vector in gene therapy, facilitating the transport of DNA or RNA into cells. In material science, it is employed as a nanoscale building block for creating advanced materials with tailored properties. Its ability to form stable complexes with metal ions also makes it useful in catalysis and environmental remediation processes.
