Laser + ultrasonic detector: scientists developed a new technique of lymphatic cancer detection

How to detect the lymphatic cancer has always been a challenge for pathology, pathologists who currently need to use more complex methods for detection, even so, the detection process still the same like a needle in a haystack.

But the recent United States University of Missouri's scientists have developed a laser pulse to scan the lymphatic cancer of sound and light technique, this technology principle is to use lymphatic cancer malignant melanoma easy to react with the laser pulse, they absorb the pulses volume variations due to temperature and reduce the rapid expansion, expansion/shrinking process would send shock waves to the outside, so that scientists can use special sensors to gather these shock waves, resulting in accurate, quickly figure out whether the patient is suffering from lymphoma and specific parts of the illness.

　　

According to the research team members John Viator explains: "this is just like a filling cakes.

In order to clarify the cake in the filling of location, our approach is not a direct insight into the cake, but using an ultrasonic probe at most likely put the filling of the site, if you detect a signal, then the site is filling. This approach greatly saves doctors check for lymphoma in time and costs. ”

For the month of July, 2009 Viator in the biomedical engineering magazine published an article entitled "the Sentinel lymph node in malignant melanoma detection method of sound and light", at present he is Professor of the University of Missouri-Jae Kwon cooperation to carry out the studies.

Currently, the research team is examining how to use gold nanoparticles to detect cancer cells do not contain melanin to let this kind of sound and light detection technology can be applied to other forms of cancer as the detection of breast cancer cells.

"Lymphatic cancer malignant melanoma in melanocytes, and breast cancer cells do not contain any pigment, so we are unable to use General laser irradiation of these cells to make them respond.

But we are currently on a such a colorless cancer cells for dyeing of nano-materials, so that you can put our detection methods for promotion to the various forms of cancer detection. ”

Viator also expressed his hope that the detection methods as soon as possible be commercialization, and stated that such detection tools "is a powerful tool in the fight against cancer."

In addition, the research team for this kind of sound and light detection method of the latest research results in the next few months in the biomedical engineering magazine will publish on.
