7.5.2 PDA-based Multifunctional Microfluidic Sensor System

Radislav A. Potyrailo, Andrew Leach & William G. Morris
We demonstrate a personal data assistant (PDA)-based analytical platform that provides detection, fluid manipulation, computing, and communication capabilities for multi-functional chemical analysis. This multifunctionality is provided by integrating the PDA with a microfluidic system, solid sensing films, and a micro-pump operated by PDA. The applicability of our approach for chemical detection in water and air was illustrated using a built integrated circuit board with eight surface mounted light source-detector opto-pairs with peak emission at 560...
