Janus nano-/micro-motors as self-propelled biosensors. (a) DNA detection based on silver ion enhanced self-propulsion of Au–Pt nanomotors. Optical images superimposed with straight-line track lines show the distance travelled by the Ni-coated Au–Pt nanomotors in H2O2 fuel after DNA hybridization.

(b) Schematic illustration showing the effect of the self-propulsion of Janus micromotors in inducing fluid mixing in microarray–based immunosensing systems.
