T-ray breakthrough could make detecting disease far easier

examining very small objects such as the interior of biological cells where it might be possible to detect diseases or abnormalities. T-rays could also be directed to the interior of objects which could be useful in applications like endoscopic probing for cancerous cells or explosive detection.

"This is a significant development that would allow unprecedented accuracy in studying tiny objects and sensing chemicals using T-rays" said Dr Stefan Maier, of the University of Bath's Department of Physics, who leads the research.

"Metal wire ordinarily has a limited ability to allow T-rays to flow along it, but our idea was to overcome this by corrugating its surface with a series of grooves, in effect creating an artificial material or 'metamaterial' as far as the T-rays are concerned."

"In this way, the T-rays can be focused to the tip of the wire and guided into confined spaces or used to detect small objects, with important implications for disease detection or finding explosive that are hidden."
