The major fact for the deaths is due to the time factor it demands to detect the infection. It takes many days in identifying the bacterial responsible for the infection. Shana Kelly and Brian Lam, University of Toronto have designed a microchip which detects the bacterial involved in the sample and also whether the bacteria possessed any drug resistance in minutes.

The chip involved solution based circuit concept that used liquids in which patient samples were immersed. The results are obtained within 2 minutes using biomolecule-specific microsensors. The results include a quick screening of multiple bacteria or viruses that produces similar symptoms.
