endoscope

A scientist has designed a 'endoscope' capable of tracking the gastrointestinal tract to tell doctors all that happens without having to mobilize bulky equipment.

German engineers have built an endoscope for medical use that is just as small as a raw salt grain.

German researchers have created a microscope with a size no larger than a grain of salt, according to a study published in the journal Nature Photonics.

British and German researchers say they have successfully built the first control system for the endoscope.
