The U.S. military has a continued interest in the development of handheld, field-usable sensors and test kits for a variety
of diagnostic applications, such as traumatic brain injury (TBI) and infectious diseases. Field-use presents unique
challenges for biosensor design, both for the readout unit and for the biological assay platform. We have developed
robust biosensor devices that offer ultra-high sensitivity and also meet field-use needs. The systems under development
include a multiplexed quantitative lateral flow test strip for TBI diagnostics, a field test kit for the diagnosis of pathogens
endemic to the Middle East, and a microfluidic assay platform with a label-free reader for performing complex
biological automated assays in the field.
