Dr. Dao Nguyen and Dr. Sara Mahshid receive MI4 Seed Funding to develop an ultrasensitive colorimetric fluidic assay for rapid phenotypic antibiotic susceptibility testing. Antibiotic resistant bacteria are responsible for 700,000 deaths annually, a figure that is projected to rise to 10 million deaths per year by 2050 if no action is taken to halt this global threat. The overuse of antibiotics and the prescription of antibiotics to which bacteria are not susceptible, contribute to the rise of antibiotic resistance. This proposal will develop an ultrasensitive colorimetric fluidic assay for rapid phenotypic antibiotic susceptibility testing (AST). The project is anticipated to reduce the turnaround time of the AST to less than 1 hour compared to 3-4 days using conventional AST methods.
