There is an urgent need for new technologies to enable convenient, inexpensive and rapid analyses of environmental samples. The past 10 years has witnessed a fast-growth of a new technology called lab-on-a-chip (LOC). LOC employs a microfluidic device as its platform and integrates multiple functional components, such as pumps, valves, and detector, on a single small device. The low internal volume associated with LOC not only reduces the consumption of samples and reagents but also generates minimal amount of waste, which is beneficial for environmental pollution control. Moreover, the low cost in fabrication and maintenance, the increased portability, and shortened analysis time make LOC more appealing for the remote site environmental analysis. This talk will focus on the method development of LOC devices for environmental analyses. Real-time monitor of inorganic species (sulfate and nitrate) in aerosol will be presented. Other potential applications of LOC for environmental analyses will be discussed.
