Nanoscale PIV and Electronic DNA (E-DNA) sensor - Patrick Freudenthal
We propose to develop and pursue commercialization of a Particle Image Velocimetry (PIV) system specifically designed to investigate the fluid mechanics of near-wall phenomena, such as slip flow and boundary layer regions in micro/nanofluidic devices. The research will focus on measuring fluid flows near a micro/nanofluidic device wall with an out-of-plane resolution of 100 nm, and with a temporal resolution of 1 ms. The instrument will measure velocity in nanochannels down to 100 nm.




The overall system design will be given high importance in balancing cost and functionality. For example, by using diode lasers, and streamlining the imaging optics, the cost of the instrument should be reduced by approximately ~$30,000 – $40,000. This will increase market acceptance, thereby allowing micro/nano-PIV to be a mainstream desktop instrument used by a large number of micro/nano device research laboratories and companies.
