Rapid, reliable on-site drug detection using wearable sensor

Researchers in South Korea have successfully developed a wearable sensor that can detect illegal drugs in sweat by using nanomaterials technology that amplify the optical signal of narcotics to a flexible, body-worn material.The technology enables fast and highly sensitive drug detection: the sweat patch is attached to the skin for a certain period of time and then irradiated with light for testing. It only takes one minute without requiring additional process.
