Microengines meet microarray technology. The transport of a target molecule toward a sensing surface can play a critical role in biodetection performance. The mixing induced by the motion of self-propelled micromotors can assist such transport and consequently enhance the performance of surface–based biosensing systems, particularly in microarray–based immunosensing that can be extended to DNA and cell analysis.
