Title: Rapid and Non-Destructive Detection of Wound Infection


Invention: The technology utilizes a smartphone as a point of care diagnostic to identify species of bacteria in a wound via light scattering.


Background: The cost for chronic wound care, which is estimated to be $25 billion annually, is mainly due to improper selection of antibiotic treatment and the need to treat an infection quickly. The current method of diagnosing infections is a tissue biopsy and swab culture, a process that can take hours to complete and requires additional resources. In general, if a bacterial species is unknown, broad-spectrum antibiotics are used, which increases the risk of drug resistance.
