Title: Chemoresponsive Nanofluidic Pump That Turns Off in the Presence of Lead Ion

Journal Article · · Analytical Chemistry

There are many applications that require the integration of a pump and a chemical sensor so that the solution being pumped can be analyzed in real time for a specific chemical species and the flow adjusted according to the measured concentration of that species. In this paper, we describe an alternative strategy: a chemoresponsive pump where a single device acts as both the sensor and pump simultaneously. We demonstrate this concept with a nanofluidic Pb2+-responsive pump that uses electroosmotic flow as the pumping technology, and a Pb2+-binding ionophore that allows the device to selectively respond to Pb2+. The pump yields high flow rates at low Pb2+ concentrations (<1 μM), but flow rate decreases with concentrations above this threshold and ultimately goes to zero at concentrations above 100 μM.
