CTS-0238689E. FurstU DelawareTwo models are currently used to understand the rheology of gels: fractal- and percolation-based. The conclusions of each approach rely on the mechanics of particle chains that form gel backbones. The PI proposes to directly measure the microrheology of the gel backbone using optical micromanipulation, such as Optical 'tweezers', and probe microrheology based on the motion of embedded particles induced by magnetic or optical forcesThe education program is mostly based on broad distribution of the course material and promoting interdisciplinary education.

CTS-0238689E。目前有两种模型用于了解凝胶的流变学：基于分形的和基于膨胀的。 每种方法的结论都依赖于形成凝胶骨架的颗粒链的力学。PI建议使用光学显微操作直接测量凝胶骨架的微观流变学，例如光学“镊子”，以及基于磁性或光学力引起的嵌入颗粒运动的探针微观流变学。
