Dendritic polymer architecture allows for the development of new therapeutics that directly target cancer cells and largely bypass healthy cells. Clusters of these polymers can be combined into more complex structures with several different subunits, each with its own function, be it targeting, imaging or therapeutics. This technology can be expanded by developing single-function dendrimer modules linked by complimentary oligonucleotides. Thus, producing multifunctional therapeutics that can be customized to a specific patient's needs.
