This presentation covers cost effective and portable lab-on-a-chip and biosensor approaches for on-site detection and analysis. On-site detection of pollutants and pathogens is highly desired for environmental, biomedical, and food safety applications. One of the challenges in off-the-bench detection is handling and manipulation of liquid samples. Recent developments in lab-on-a-chip and biosensors having passive microfluidic control schemes will be demonstrated for on-site detection applications. Simple and reliable detection is another challenge, and the presentation will address both optical and electrochemical detection options. Other key challenges in practical applications of lab-on-a-chip platforms will also be reviewed and discussed.
