Chemically Amplified Response Strategies for Medical Sciences

技術優勢

Potential advantages from molecularly engineering linear dual-response mechanisms into the backbone of polymeric nanoparticles include enhanced stability and prolonged shelf life, while also increasing the response sensitivity and efficacy of targeted delivery to diseased environments. In addition, this polymeric nano-carrier technology may reduce overall toxicity by decomposing into easily excretable fragments. This technology is designed to be versatile where the triggering group can be sensitive to a number of wavelengths.

詳細技術說明

Researchers from UC San Diego have designed a new light-sensitive degradable polymer containing a quinone-methide, self-immolative moiety, which can be triggered to degrade through multiple light-sensitive groups. Nanoparticles formulated from this polymer are capable of releasing their molecule payload upon irradiation by UV and NIR light. The details of this technology are published in the patent application (2011/038117).
