Abstract

We describe a simple micropump for disposable microfluidic devices. The pump is constructed using a freeze-dried disc of a superabsorbent polymer (SAP). The disc absorbs a solution in a flow channel and swells upward in a pumping chamber. Despite the simple structure of this device, the rate of absorption remains constant and can be adjusted by changing the composition of the SAP, its size, the dimensions of the flow channel, and the medium to be absorbed. The pumping action can be initiated by applying an electrical signal using a switchable hydrophobic valve. The integrated approach of SAP pump and switchable valve could facilitate the automatic processing of many solutions required for bioassay.

Data from: A simple micropump based on a freeze-dried superabsorbent polymer for multiplex solution processing in disposable devices

The data present mainly the performances and characterization of the superabsorbent polymer-based micropump. Specifically, the data include the comparison of the absorbing rate and capacity using SAP, comparison of SAP with other absorbent materials,comparison of the SAP pump with tissue paper pump, influence of the SAP-CA ratio on rate of absorption, influence of NaCl on the rate of absorption of SAP, solution displacement by the SAP pump, the influence of the size of SP disc, dimension of the flow channel on the pumping rate and current response on different concentration of glucose. Supporting movie 1, 2, 3 and 4 show the operation principle of the SAP pump, continuous flow of solutions for long time, multiple pumping realized with SAP pump and multiplex processing of solution with SAP pump and switchable valve respectively.
