Laser Sensor Speeds Up Salmonella Detection in Food Samples
Laser Sensor Speeds Up Salmonella Detection in Food Samples A new laser sensor can identify salmonella bacteria in food samples as much as three times faster than conventional detection methods. Developed by researchers at Purdue University, the sensor, called BARDOT scans bacteria colonies and generates a distinct fingerprint to identify the bacteria in less than 24 hours. Traditional methods can take 72 hours and often require artificial alteration of the colonies.
