Invented "pencil" that detects cancer for 10 seconds

Believe it or not

Scientists at the University of Texas have invented a handmade pencil shape that he claims can detect carcinogenic tissue. This is already a good news in itself, but what's most interesting is that the "pen" can do that in just 10 seconds. An unbelievable new piece of technology was created.

The handheld device, known as the MasSpec Pen, could revolutionize tumor surgery dramatically reducing the risk of cancerous tissue leaving inside the patient, resulting in a reduction in the chance of the tumor returning. The surgeons are now challenged to find the border between tumor and normal tissue. In some types of tumors this is obvious, but in some cases the limits do not seem so obvious. This powerful pencil should be of help to doctors in the mission to completely eliminate the tumor.

Scientists have confirmed in Science Translational Medicine that the device can measure thousands of molecules present in the sample in just 10 seconds and with tests suggesting that the test is exactly 96 percent of the time. How does it all work, are you wondering? The principle is simple.

The pencil is put on a sample of tissues suspected to be carcinogenic and then drop a few drops of water. Tissue-formed molecules enter a drop of water that is then dipped into the pen and prepared for analysis. The pen should then be put into a mass spectrometer, which scans the drop and gives an answer to the question of what chemicals are present, from which it can be concluded whether the sample is carcinogenic or not.

Currently, if a tissue sample has to be tested during the operation, the process may be slow and occasionally inaccurate. The tissue should be removed and sent for evaluation, which may take up to half an hour while the patient is still under anesthesia. This increases the risk for the patient, the infection and the negative effects of long-term anesthesia.

"Every time we have to offer the patient a more precise, faster and safer operation," said James Suliburk, a surgeon from Baylor Medical College who co-developed the pen development. "This technology allows all these three assumptions. "

Revolutionary pencil has been tested on a total of 253 samples so far, and will continue to be tested until next year when it is expected to start operating in the operating flashes. For now, pencils can take 1.5 mm of tissue sample, but scientists are already on the path to making new pencils that will take larger and smaller samples, writes IFL Science .
