Microfluidic Control Technologies for In Situ Sensing Applications

点击翻译按钮获取中文摘要

The purpose of the Pathfinder application is to secure funding to support patent application through the UK patent office for two key technologies incorporated within the next generation of the lab-on-chip microfluidic chemical sensor currently under development at the National Oceanography Centre. Both technologies relate to fluidic control: The first technology is a membrane based valve that can be configured for either passive one-way flow or active control when power is supplied, and the second is a syringe pump with bespoke control electronics for accurate fluid dosage and optimised power consumption that make it suitable for long term autonomous operation in the field. The ocean science community will be the primary beneficiary of this set of technologies and their subsequent commercialisation.Keywords: microfluidic on-chip valve; micro pump technology; microfluidic reagent-based chemical analyser; in situ sensors; lab on chip technology
