Nanomachinery lights up: "A light-activated switch to turn nanomachines on and off has been developed by Japanese researchers. The team showed how tiny tweezers made with DNA could be triggered to open and close in response to UV and visible light. The clever mechanism is hoped to find useful roles in designing future nano-robots.
DNA is a versatile building block to construct nanomachinery that is small enough to interact with single molecules. But these nanomachines usually require a source of 'fuel' to trigger activity: typically small DNA fragments that are added each cycle. The problems associated with this process are delays in activating and deactivating systems, and the build up of waste products that can inhibit movement."
