This is particularly important for the creation of completely human - made mixtures because the self - motile particles that can be manufactured to stand in for bacteria, such as Janus particles, light - activated particles, polymer
based nanomotors and robotic swarms, are difficult to manufacture.
«Platinum and gold are not harmful to the body in these small quantities,» he says, adding that his team's work paves the way for creating
nanomotor -
based sensing systems for monitoring chemicals — including glucose — in the body, although a practical application is still years away.
