Presentation Abstract
Grantee Research Project Results
Environmental Applications/Implications:
“Lab-on-Chip” technologies can dramatically change the speed
and scale at which environmental analyses are performed. We introduced
new and innovative nanomaterial-based strategies for enhancing the performance
of microchip devices for environmental assays. These developments indicate
that nanomaterials and microchip devices hold a great promise for environmental
monitoring of priority pollutants. The resulting microfluidic device will
enable transporting the entire laboratory to the sample source, and will
offer significant advantages in terms of speed, cost, efficiency, sample/reagent
consumption, and automation.
