2010 R&D 100 Winner
The Acoustic Wave Biosensors for Rapid Point-of-Care Medical Diagnostics is the first device to identify a range of pathogens while the patient is in the office, enabling for more accurate diagnosis or treatment. The hand-held, battery-powered, portable detection system, developed by Sandia National Laboratories and Univ. of New Mexico Health Sciences Center, both of Albuquerque, N.M., identifies pathogens in nasal and throat swabs, saliva, urine, and blood, and can perform environmental detection from water, air, soil, food, and surfaces.
The detection system employs a shear horizontal surface acoustic wave biosensor array functionalized with selective ligands. The sensor array weighs the amount of pathogen bound to its surface by these ligands.
To use, the health technician inserts a microfluidic sensor cartridge matched to the suspected pathogen into the instrument. A drop of the sample is placed on the input port where capillary action draws it on to a sensor. The instrument's software, run on a PDA or computer, indentifies the pathogen and displays the result.
