Medical diagnostic capabilities for extreme environments are limited in nature to single marker type assays. A more adaptable device would better serve applications in emergency first response, the battlefield, low-resource countries facing disease outbreaks, and long-duration space flights.
We developed a handheld device for medical diagnostics in extreme environments that provides sensitive and specific detection of biomarkers with an emphasis, initially, on radiation exposure. The highly adaptable microfluidic device uses a pump-less mechanical method to move, control, order, and layer fluids in the platform to decrease complexity while enabling simultaneous cell separation and plasma generation for differential blood cell counts and biomarker assay panels. Our results provide a test bed for producing and characterizing a host of novel proteins to analyze their molecular and cellular functions.
This project addressed Lawrence Livermore National Laboratory's chemical and biological countermeasure mission research challenge and the Laboratory's biosecurity mission area. Our research advances ongoing measurement science (biophotonics) and threat biology. The project leveraged Livermore's core competencies in bioscience and bioengineering, and the Laboratory's radiation exposure biomarker work provides a biological platform to demonstrate the device.
