A Method of Developing Single Molecule DNA Nanoparticles as Diagnostic and Therapeutic Agents
Offers a powerful therapeutic platform based on DNA—a molecule approved for in vivo human use. Avoids the conjugation chemistries typically associated with conferring target specificity, biocompatibility, and drug incorporation. Provides a multifunctional platform for integrating many cancer therapeutic techniques.
Leveraging DNA’s inherently unique properties and ease of synthesis, a UC San Diego researcher has developed a methodology for the construction of large libraries of DNA nanoparticles and a process for the iterative selection of particles with desired properties. When coupled with DNA’s other structural, functional, chemical, and informatic properties, this technology permits the efficient customization of multifunctional particles for biomedical and therapeutic use. Leveraging DNA’s near anti-body specificity, practically non-toxic biocompatibility, and other desired properties, this technology provides a powerful approach for designing custom targeted therapeutics and diagnostic probes in a variety of applications.
