Researchers have pushed forward the boundaries of biomedical engineering one hundredfold with a new method for DNA detection with unprecedented sensitivity.
UMass Amherst researchers have pushed forward the boundaries of biomedical engineering one hundredfold with a new method for DNA detection with unprecedented sensitivity.
That's where this method is different. The test sample is put within an alternating electric field. Then,"We let the DNA dance," he says."When the strands of DNA dance, they have a specific oscillation frequency." Researchers can then read samples to see if there is a molecule moving in a way that matches the movement of the target DNA and easily distinguish it from different movement patterns. This even works when there is a very low concentration of the target DNA.
Another benefit: it's portable. Ping describes the device to be similar in size to a blood sugar test tool, which opens the doors to improvements in health on a global scale."It can be used at places where resources are limited. I went to a country and the doctor usually goes to a village once or twice a year, and now, maybe they can have a base that has this kind of tool and they'll have the chance to test for it quickly and easily.
