This research will focus on the development of an ambient aerosol sampling system based on Lab-on-a-Chip (LOC) technology. The advantage of this new technology is the size of the sampling system, low cost, and the ability to provide in situ analysis of certain chemical characteristics using a colorimetric detector. The analytical detector will be housed in a single microchip, along with the microfluid component that actually captures and transports the aerosol particles to the detector. The entire chip unit is placed in an aerosol collection system (impactor).The goal of this research is to produce an integrated unit that can be used for in situ analysis of ambient aerosol samples. While the technology of microfluidics has been demonstrated over the past several years, as well as that for the detector, an integrated system has not been attempted yet. This high risk research project is potentially transformative to the atmospheric sciences community in that its success may ultimately lead to the development of a new generation of lab-on-a-chip systems that will be extremely small, lightweight, portable, inexpensive, and have fast, in situ analysis response times.

本研究将致力于基于芯片实验室（Lab-on-a-Chip）技术的环境气溶胶采样系统的开发。 这种新技术的优点是取样系统的尺寸小，成本低，并且能够使用比色检测器对某些化学特性进行现场分析。 分析检测器将与实际捕获气溶胶颗粒并将其输送到检测器的微流体组分一起沿着容纳在单个微芯片中。 整个芯片单元被放置在一个气溶胶收集系统（撞击器）。本研究的目标是生产一个集成的单元，可以用于环境气溶胶样品的原位分析。 虽然在过去几年中已经展示了微流体技术以及用于检测器的技术，但尚未尝试集成系统。 这个高风险的研究项目对大气科学界具有潜在的变革性，因为它的成功可能最终导致新一代芯片实验室系统的开发，这些系统将非常小，重量轻，便携式，价格低廉，并且具有快速的原位分析响应时间。
