For applications in drug delivery, “smart” materials have been designed to respond to conditions within microenvironments of tissues or cells. The present invention features stimuli-responsive cross-linked hydrogels that respond to specific metabolites of disease. For example, protein-polymer materials of the present invention are configured to release their drug cargo upon encountering the higher lactate concentrations within tumor microenvironments.
在药物传递应用中,已经设计了能够响应组织或细胞微环境条件的“智能”材料。本发明涉及对特定疾病代谢产物作出响应的刺激响应型交联
水凝胶。例如,本发明的蛋白质-聚合物材料被配置为在遇到肿瘤微环境中更高的
乳酸浓度时释放药物载体。
