Beauty invented nanoscale DNA detector
American researchers have developed a very small research tool, the DNA detector, which functions as an existing gene chip. Gene chips are often used to simultaneously detect mutations in thousands of genes or to find diseases. Causes. But the tool is only nano-scale, and the research object is less than tens of thousands of human hair.
Lin Sai said in his research results: "This microchip can be studied inside a single cell." Existing gene chips can only study the entire group of cells. This new technology makes it possible to perform more sophisticated analysis, for example, it can detect the genetic changes of cells one by one. The study was conducted by Yan Yi, a researcher at the Center for Single Molecular Cell Biophysics at the University's Institute of Biodesign. Lindsay said: "This nano-detector can be synthesized in a water-soluble solution, so the production cost is low." He said that the new system uses DNA characteristics to create different nanostructures, which is only the initial application of nanotechnology.
Lin Sai pointed out: "I think nanotechnology has great potential. We are only taking a small step in this direction." - Shanghai Medical Device Industry Association website
