Engineered materials that integrate advances in polymer chemistry, nanotechnology, and biological sciences have the potential to create powerful medical therapies. Dr. Khademhosseini’s group is interested in developing ‘personalized’ solutions that utilize micro- and nanoscale technolgoies to enable a range of therapies for organ failure, cardiovascular disease and cancer. In enabling this vision he works closely with clinicians (including interventional radiologists, cardiologists and surgeons). He has developed numerous techniques in controlling the behavior of patient-derived cells to engineer artificial tissues and cell-based therapies. His group also aims to engineer tissue regenerative therapeutics using water-containing polymer networks called hydrogels that can regulate cell behavior. Specifically, he has developed photo-crosslinkable hybrid hydrogels that combine natural biomolecules with nanoparticles to regulate the chemical, biological, mechanical and electrical properties of gels. These functional scaffolds induce the differentiation of stem cells to desired cell types and direct the formation of vascularized heart or bone tissues. Since tissue function is highly dependent on architecture, he has used microfabrication methods, such as microfluidics, photolithography, bioprinting, and molding, to regulate the architecture of these materials. He has employed these strategies to generate miniaturized tissues. It is anticipated that such approaches will lead to the development of next-generation regenerative therapeutics and biomedical devices.

整合了高分子科学,纳米技术,以及生物技术的生物材料有潜力来实现很多生物医疗应用。Khademhosseini教授的实验室致力于开发基于微制备及纳米技术的“个性化”疗法,例如治疗器官退化、心脑血管疾病、以及癌症。他与临床医生紧密合作来推进这个愿景,包括介入放射科医生,心血管病医生,以及外科医生。他开发了多种技术来改造病人细胞来做人工组织或者细胞疗法。他的课题组同时也开发组织再生疗法,比如说使用水凝胶网络来控制细胞的行为。他开发了一个可光交联的复合水凝胶,并在其中整合了生物大分子、纳米粒子来调控水凝胶的化学,生物学,力学,及电学性质。这些水凝胶能够促进干细胞分化成目标细胞,并直接形成血管化的心肌组织以及骨组织。因为组织的功能高度取决于它的结构,他还医用微制备技术来控制生物材料的结构,包括微流控、光刻、生物打印、和模具成型。他用这些技术制造了很多微型组织。这些技术有望引领下一代再生疗法和生物医疗装置。
