Abstract

Liquid transportation without employing a bulky power source, often observed in nature, has been an essential prerequisite for smart applications of microfluidic devices. In this report, a leafinspired micropump (LIM) which is composed of thermoresponsive stomata inspired membrane (SIM) and mesophyllinspired agarose cryogel (MAC) is proposed. The LIM provides a durable flow rate of 30 μl/h·cm2 for more than 30 h at room temperature without external mechanical power source. By adapting a thermo-responsive polymer, the LIM can smartly adjust the delivery rate of a therapeutic liquid in response to temperature changes. In addition, as the LIM is compact, portable, and easily integrated into any liquid, it might be utilized as an essential component in advanced hand-held drug delivery devices.
