- Abstract
- Microfluidics offers great potential for biomedical applications, but the complexity, inconvenience, and low pumping equipment accessibility of operating microfluidic devices have limited their widespread use. Here we describe an open-source, programmable smart (OS) pipette as an easy-to-use, simple, handheld microfluidic pump that overcomes the major limitations of previous commercial- or research-level pumps for microfluidics. The OS pipette pumps fluid into a microfluidic device by precisely controlling the position of the plunger of a positive-displacement micropipette with stepper motor control. The intuitive pumping mechanism of the OS pipette enables the novel features of simple fabrication, straightforward device operation, and precise, predictable, and programmable flow-rate generation as an open-source pumping tool. Controlling the OS pipette using an open-source microcontroller board not only allows straightforward generation of constant flow rates with simple source code commands, but also permits varying flow rates to be programmed (including stepwise increase and decrease of the flow rate over time, and flow-rate pulse generation). We successfully validate the OS pipette's capabilities for portable microfluidic cell separation and counting. The OS pipette has promise as a rapidly evolving and potentially transformative pumping tool that freely allows unrestricted use, distribution, reproduction, and modification even by non-expert users, and further enables diverse usages, even beyond microfluidics.
