The White Research Group develops integrated microsystems for the diagnosis and study of disease at the cellular and molecular level. Using a combination of microfabrication techniques, we are implementing micro total analysis systems (uTAS) for three major research thrusts.
- Infectious disease detection. Using novel techniques, we aim to implement a uTAS that concentrates pathogens from large volume samples, recovers nucleic acids, and quantifies pathogens in the sample based on DNA signature biosensing.
- Understanding cancer metastasis. We are developing a new on-chip assay to identify and enrich highly tumorigenic cells using techniques in microfabrication, chemistry, and cancer biology.
- Point-of-sample chemical/biomolecule detection. We have developed novel 3D optofluidic surface enhanced Raman spectroscopy (SERS) scaffolds in uTAS devices to enable low-cost portable detection of chemicals and biomolecules, including pesticides, explosives, and industrial toxins.
