The device, developed by scientists from Johns Hopkins University, it takes a tissue to biopsy. Protopit cheap autonomous micro robot will be able to extract part of the internal organs and deliver cells for research. Taking samples for biopsy now performed using endoscopic instruments, which have limited maneuverability, and can not penetrate into the inaccessible location of the human body.
A novelty of American researchers without such deficiencies. It is a five-pointed star of a millimeter in size, capable of "closed", taking samples of tissue. Consists of several layers of metal and polymer materials, and that is important - do not require any control from outside. The materials from which it was created, responding to temperature and certain chemicals.
A layer of polymer can reduce its stiffness at temperatures above 40 degrees or under the influence of biological reagents. This polymer is "released" a layer of metal, allowing the "star" close and take samples of tissue. So far, only the developers presented their model, and will take time to refine it. Complete surgical instruments have not yet will soon come into mass production.
