The scientist invents the blame of skin cancer to injure sexual optics to diagnose a method

The chemist that comes from Duke university people the 3 dimension image that confirms system of a kind of laser can get chemistry and structure are changed under human skin surface layer recently, this is the first pace that marchs toward malign skin tumour to be not surgical operation to diagnose a technology. Chemistry of university of ? ? Duke, radiology and biology medicine project teach Warren Warren expresses: "At present method of surgical diagnostic standard is to cut below one small organization, organize section in the observation below microscope next. And what we should do is to try to find what do not need to cut next organizations to diagnose a method. And what we should do is to try to find what do not need to cut next organizations to diagnose a method.. One of composition of cell of ? ? blood red -- hematin and skin pigment -- of melanin distributinging is the inchoate signal that skin cancer grows. But because the skin is right smooth scattering is very strong, because this simple microscope cannot decide a these elements, unless they are located in surface layer. And although laser can penetrate deeper, and make certain element gives off light, but hematin and melanin cannot use method of this one party. Group of ? ? Warren found a kind of skill recently, the hematin that makes problem organization medium and melanin can pass height to controlled laser is aroused and give off light. Exquisite of this one technology used two bundles of laser, each hairdo gives the light of different color. To assure the skin won't overheat, laser pulse must measure level in flying second. ? ? uses the light that hematin and melanin give out, can magnify outside the skin structure, and benefit gets cellular measure picture with the computer. New technology can make the doctor sees surface layer skin is the following the structure of 1 millimeter, this to diagnosing character is already enough. ? ? is on the conference of international of technology of a laser May, the group made the report that how makes hematin visible in mice skin blood-vessel. Warren expresses, his group is in and the skin and cellular biology fasten collaboration to develop clinical test.
