The research in my laboratory enables the design and processing of macromolecular nanoscale materials (nanomaterials) to address important problems at the crossroads of biology and materials science. A stimuli-responsive degradation (SRD) platform involves the incorporation of dynamic covalent bonds (or cleavable linkages) into nanomaterials, which can be cleaved in response to external stimuli (acidic pH and light as well as reductive, oxidative, and enzymatic reactions), when required. SRD-exhibiting nanomaterials are designed to be degradable upon the cleavage of dynamic linkages, thus allow us to change physical property, control morphology, and importantly enhance drug release.

我实验室的研究使大分子纳米材料(纳米材料)的设计和加工能够解决生物学和材料科学十字路口的重要问题。刺激响应降解(SRD)平台涉及将动态共价键(或可断裂的键)结合到纳米材料中，这些键可以在需要时对外部刺激(酸性pH和光以及还原、氧化和酶反应)做出反应而被切割。展示SRD的纳米材料被设计成可以在动态连接断裂时被降解，从而允许我们改变物理性质，控制形态，并且重要的是增强药物释放。
