    Low cost portable flow cytometry - NIH RR020064 R21/R33
    This is a grant to develop a low cost portable flow cytometer for use in resource poor settings for the diagnosis of critical diseases such as HIV. In this work we are developing new technologies for fluidics, optics, and data acquisition that will transform a flow cytometer from a costly bulky clinical instrument into a true point of care device.

    Next Generation Large Particle Sorting
    Overall Project Center Goal: To provide a national resource in flow cytometry with research, collaborations, service training and dissemination activities. Project Lead on - Next Generation Optically Activated Large Particle Sorting. With few exceptions, cell sorters rely on droplet based sorting of particles. While this works well for smaller particles, because of fluid dynamic effects the size of particles that can be sorted is limited to ~100 µm with rates of less than 1000 events/sec. Using a combination of synchronous particle delivery, droplet on demand, parallel flow cells, low cost excitation and emission detection components and miniaturized data acquisition we will develop high-thoughput large particle sorting systems. Our target is to be able to sort particles up to 1 mm at rates of more than 10,000 events/sec. This will have large impacts on combinatorial library screening and multi-cellular organism sorting.
