Researchers in South Korea have successfully developed a wearable sensor that can detect illegal drugs in sweat by using nanomaterials technology that amplifies the optical signal of narcotics to flexible, body-worn material.
Led by Dr. Ho Sang Jung, the research unit is part of the Korea Institute of Materials Science(KIMS), a government-funded research institute under the Ministry of Science and ICT.
The technology enables fast and highly sensitive drug detection: the sweat patch is attached to the skin for a certain period and then irradiated with light for testing. It only takes one minute without requiring an additional process.
The traditional drug detection process requires a complex method of extracting suspected drug components from biological specimens including hair, blood, and urine, and then analyzing drugs through gas or liquid chromatography-mass spectrometry (GC/MS or LC/MS).
It takes longer testing tim
