he biological microcavity laser, one microlaser beam is all that's needed to intersect cells passing in a channel over the surface of the glass. More channels and more lasers can be added to increase the speed of the technique. Recently published technical papers about the project have appeared in The Journal of Biomedical Microdevices and the Proceedings of the Biomedical Optics Society (SPIE).

Preliminary discussions are being held with biotech companies interested in commercializing the technique.

With further development, the microsensing device could also be deployed as an inexpensive, fast monitor of biological and chemical constituents of groundwater, waste fluids, or explosive chemicals. It is already able to detect other blood protein abnormalities, such as sickle cell anemia.
