A team of scientists from the University of California at San Diego recently developed nanorobots to destroy bacteria and detoxify blood. The broad strokes: The nanorobots, which are made out of gold, are 25 times thinner than a human hair. They move in response to ultrasound stimulation, which means they require no fuel. Scientists coated the gold nanarobots with a hybrid ‘skin’ built from platelet and blood cell membranes, which serves two main functions: It stops proteins from attaching themselves to the nanorobots, a process called biofouling — which would render them useless. The membranes are like a VIP pass…
