Instead of using chemical signaling that relies on diffusion to reach its target, these antibodies will communicate with rapid acoustic pulses. Instead of proteins, they will be made using much more durable polymers or even diamond. These antibodies will move through the bloodstream more quickly than other cells in the body, and will take up less space and resources, meaning that there will be room for many more. [ read more ]
