New device can extract human DNA very fast

Engineers have created a device that can extract human DNA in a simpler and more efficient way than conventional methods. They designed microscopic probes that dip into a fluid sample and apply an electric field within the liquid. That draws particles to concentrate around the surface of the tiny probe. It takes 2 or 3 minutes to separate DNA using this technology…
