Self-powered micropumps that are turned on by the presence of their respective substrates are formed from surface-immobilized, ATP-independent enzymes. Coupling substrate-sensing with transport enables the design of devices that deliver cargo in response to specific stimuli. Demonstrated here is the release of insulin at a rate proportional to ambient glucose concentration.
