Collaborating scientists from the University of Warwick and the Chinese University of Hong Kong (CUHK) have demonstrated a method that uses terahertz radiation to improve the diagnosis of skin conditions such as eczema, psoriasis, and skin cancer.
Terahertz radiation (T-rays) falls between infrared and Wi-Fi on the electromagnetic spectrum. T-rays are able to pass through common materials such as plastics, ceramics, and clothes nondestructively, making them an attractive prospect for noninvasive inspections. Because the low-energy photons of T-rays are nonionizing, they are safe in biological settings.
