The aqueous microfluidic phase flows from left to right (blue arrows). The gas phase flows from back to front (green arrows). Analyte molecules (red spheres) diffuse from the gas phase into the liquid phase (red arrows). Nanoparticles (white spheres) suspended in the aqueous phase adsorb to suspended analyte molecules before interrogation by 658 nm laser light (red vertical beam) for detection by SERS.
Research DescriptionProfessor Meinhart's research group investigates fundamental fluid mechanics problems at the micro-scale and nano-scale, with special emphasis on transport issues in MEMS-based sensors for highly sensitive and specific detection of trace chemicals. His research group works closely with the Moskovits research group in chemistry to combine surface-enhanced Raman Spectroscopy with microfluidics.
Both experimental and numerical simulation tools are developed and utilized to investigate transport processes at the micro and nanoscales.
BiographyProfessor Meinhart completed his Ph.D and Postdoctoral work at the University of Illinois in June of 1995. Since coming to UCSB in 1996, his research has focused on developing and applying PIV to study transport phenomena in microfluidic devices. His research group is involved in the development and analysis of BioMEMS, and SERS-based ultra sensitive chemical detectors.
