This proposal is concerned with the interaction of large molecules, such as polymers or proteins, with aqueous environments. Two main projects are of particular interest: The first concerns the effects of flow and confinement of grafted, dense polymers in micro and nano-channels. Polymers in such channels can act as pressure-activated switches that restrict flow at low pressure differentials but untangle and order when the pressures between input and output ends of a channel differ signicantly. The details dynamics in such systems are not well understood.

该提案涉及大分子（例如聚合物或蛋白质）与水环境的相互作用。 两个主要项目特别令人感兴趣：第一个涉及微纳米通道中接枝致密聚合物的流动和限制效应。 这种通道中的聚合物可以充当压力激活开关，在低压差下限制流量，但当通道输入端和输出端之间的压力显着不同时，它们会解开并排序。 此类系统的细节动态尚不清楚。
