Abstract: The aim of technology is to make products in a large scale for cheaper price and increased quality. As the current manufacturing technology is at macro level but the future lies in manufacturing product at molecular level. On the basis & advent of nanotechnology one such product manufactured is pill camera. “Camera Pill” or Capsule endoscopy is a new diagnostic tool that permits a direct visual examination of the small intestine, an area of the body not previously accessible using upper endoscopy from above or colonoscopy from below. The pill, known as the Capsule Endoscopy, is about the size of a multivitamin and is swallowed with a sip of water. The pill is made of specially sealed biocompatible material that is resistant to stomach acid and powerful digestive enzymes and thus every care is taken such that the caps will not rupture or burst. Its non-invasive diagnostic alternative that is relatively quick, easy, office based test that will encourage people to see their doctors to get checked for diseases, Capsule endoscopy helps your doctor evaluate the small intestine. This part of the bowel cannot be reached by traditional upper endoscopy or by colonoscopy. The most common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine. It may also be useful for detecting polyps, inflammatory bowel disease (Crohn’s disease), ulcers, cancers, andanemia and tumors of the small intestine. It takes picture of our intestine and transmits the same to the receiver of the computer for analysis of our digestive system. This process can help in tracking any kind of disease related to digestive system.
