At the Hashemi Lab, we are working on projects concerned with the design and fabrication of microfluidic/optofluidic devices with applications to clinical diagnosis, renewable energy, and environmental monitoring.
Our primary research objective is to understand how microfluidic transport could provide a fundamental science base for novel fabrication of polymer microfibers with controlled size, shape, and molecular alignment. Computational fluid dynamics and experimental techniques will be employed to design and study characteristics of highly structured microfibers.
Also, hydrodynamic focusing of one laminar stream by another has inspired new approaches in biosensors and cell analysis. We have devised a novel system to ensheathe, focus, and separate the sample stream from the sheath streams. Using grooves at very specific orientations in the upper and lower surfaces of the microchannel, the sheath fluid is directed around the sample stream in the microflow cytometer. The dynamics of fluid flow can be reversed by reversing the direction of the forces applied to the system at low Reynolds number. Integrating the concept of “unstirring” into the groove-based sheath flow system by placing reverse grooves in the channel pointing upstream, the sample stream is separated from the contiguous sheath streams. The unsheathing capability provides the opportunity to recover particles from the sensor with minimal dilution or to recycle the sheath fluid for long-term unattended operation.
