Recently, ambulance acquired infections are of increasing concern as the scope of procedures that EMS personnel perform has increased. Cleaning assessment increases cleaning efficacy reducing acquired infections – however due to high initial cost of devices, ambulances cannot afford this assessment step. To address this, the team has created a low cost alternative to current ATP detection systems. The ATP in contaminants, combined with Luciferase, emits a light with intensity proportional to ATP concentration, indicating contamination. The team’s novel design uses a photodiode along with a Smartphone app in order to quantify light emission and provide fast, user friendly results. The light intensity this design can detect is 0.2 to 50 mW/cm2 at 520nm, a viable range for ATP detection.
