Researchers have developed a device Cellscope that could identify and track diseases like tuberculosis (TB) and malaria in developing countries with limited access to health care, or in rural areas of the U.S. A Cellscope is a cheap smart-phone microscope could bring fluorescent medical imaging to areas with limited access to health care. It captures and perform simple analysis of magnified images of blood and sputum samples, or transmit the images over the cell-phone network for analysis elsewhere. The contraption a tube like extension linked onto the cell phone with a modified belt clip--works just like a traditional microscope, using a series of lenses that magnify blood or spit samples on a microscope slide.
