Science and technology applied in medical news is commonplace, Google in March this year, a wrist strap design patents, various forms of energy pulses can be used to help treat diseases such as Parkinson's and cancer.
So far, people still talk about the "cancer" color change. Circulating tumor cells (CTCs) refers to the body of tumor cells in the peripheral blood, postoperative recurrence and metastasis in patients with malignant tumor of important reasons are also important factors leading to death in cancer patients.
However, to detect such cells is difficult, because 1 ml containing 5 billion red blood cells in the blood, which contains cancer cells have less than ten. Jack Spade iPhone 5 Case
Sonic wave from the Pokemon 20 damage to the opponent, that sound waves can give cancer shock?
Massachusetts Institute of technology, Pennsylvania State University and Carnegie Mellon University's research and development team consisting of engineers on April 6, a study published in the journal PNAS, pointed out a new way to find cancer cells in the blood--with Sonic!
At present, most of the chemicals used for cell sorting techniques need to be marked or cells under mechanical force, these methods may damage the cells. This new technology uses sound waves of isolated cells, is a relatively mild way.
Researchers have built a Microfluidic device, which includes two acoustic sensors produce sound waves. When the two waves meet, they form a standing wave. Standing waves can be in the same position, pressure nodes. Jack Spade iPhone 5 Case
Because the sound wave is tilted, so cells through micro-channel at a certain angle. Each cell will face a lot of pressure nodes,
Each node cells are further into the channel at the other end, but other cell properties (such as compression/size, and so on) will determine their distance.
Through this method, researchers cancer cells can be separated from the red and white blood cells. Original sample speeds only 1-2 mL/min; and new equipment to speed up 20 times, about 5 hours to complete a patient sample.
Through this video, we take a look at how it works:
In contrast, the acoustics are very mild, without bead, antibodies or other molecular markers, very suitable for further analysis. Currently, researchers are working to optimize device performance, further improved device detection.
