Chemotactic separation of enzymes
WebJul 1, 2016 · Recent studies showed that the diffusivity of enzymes increased in a substrate-dependent manner during catalysis. Thus, the energy released during enzyme catalysis could be used to propel nanoscale objects, e.g. molecule motors driven by enzymatic reactions.
