0529385 Brown本项目将开发一种基于电泳捕获和纳米孔释放颗粒的新方法。所提出的粒子传感器阵列将是一个全电子的、大规模制造的cmos集成设备，它将比目前的粒子测量设备小几个数量级。初步结果表明，给定孔隙的颗粒捕获时间与大于孔径的颗粒浓度有关。基础研究将表征纳米孔的粒子捕获和释放动力学作为电极激励方案的函数。将开发一种制造工艺，在CMOS电路上制造纳米孔。这样开发的传感器可用于测试水中的颗粒或测试空气中已收集颗粒的水。由于各种实际原因，颗粒测量在评估水质方面很有用。pi正在开发的方法是新颖的，代表了“尖端”纳米科学。

0529385 Brown This project will develop a new method of particle analysis based on electrophoretic capture and release of particles by nanopores. The proposed particle sensor array will be an all-electronic, mass-fabricated CMOS-integrated device, and it will be orders of magnitude smaller than current particle-measuring devices. Preliminary results demonstrate that particle capture time for a given pore is related to the concentration of particles larger than the pore diameter. Fundamental studies will characterize particle capture and release dynamics of the nanopores as a function of electrode excitation schemes. A manufacturing process will be developed to fabricate nanopores on top of CMOS circuitry. The sensor thus developed could be used to test for particles in water or to test water into which airborne particles have been collected. Particle measurements are useful in assessing water quality for a variety of practical reasons. The approach being developed by the PIs is novel and represents "cutting edge" nano-science.
