Abstract:
We report the fabrication of pillar[5]arene (P[5]A) stabilized MCs via the self-assembly and crosslinking of P[5]A nanoaggregates at the liquid-liquid interface. These MC microengines turn on fluid flow in the presence of paraquat (PQ) due to "host-guest" molecular recognition. The microengines could be useful in designing non-mechanical micropumps, powerless microfluidics, and diagnostic devices.
