veloped a bioluminescence-based assay coupled with a portable device that works with smartphones and laptops to do on-site testing for harmful E coli in food samples.
The silicon photomultiplier (SiPM) device uses low light to from the bioluminescent assay to detect the presence of bacteria that cause foodborne illnesses in food samples.
The Purdue team also created an electrical circuit with an amplifier, comparator and micro-controller to send the data to laptops and smartphones via Bluetoot
