Thermoresponsive biodegradable polymers with tunable temperature-dependent solubility

總結

Targeted drug delivery is being explored as an alternative to chemotherapy in cancer treatment. While many anti-cancer agents have been identified, applications have been limited due to temperature sensitivity and cytotoxicity of the carrier polymer. This technology describes methods for creating biodegradable polyacetal-based polymers with a specified lower critical solution temperature (LCST). This technology provides pathways for delivery of a range of novel pharmaceutical agents.
