Magnets can be used to make DNA - based nano robots move on faster and quicker than previously possible . Ohio State University researchers developed a magnetic control system which reduced the response time of prototype mini ##max components from several minutes to under a minute . Previously scientists could only move molecules indirectly by inducing chemical reactions or introducing molecules . The effect could mean that nano robots could one day make objects such as drug - delivery devices with the same speed and reliability of their full - size counterparts .
Magnets can be used to make DNA-based nano robots move on demand and quicker than previously possible. Ohio State University researchers devised a magnetic control system which cut the response time of prototype mini robot components from several minutes to under a second. Previously scientists could only move DNA indirectly by inducing chemical reactions or introducing molecules. The discovery could mean that nano robots could one day make objects such as drug-delivery devices with the same speed and reliability of their full-size counterparts.
