Microfluidics deals with the behaviour, precise control and manipulation of fluids that are geometrically constrained to a small, typically sub-millimetre, scale at which capillary penetration governs mass transport. - Our goal is to develop custom DIY microfluidics chips (currently as a proof of concept), and perform lab-on-a-chip like experiments.

Development of our own microfluidics devices


Version History


V 0 and V 1

Version Zero was our first shot at microfluidics. We wanted to perform a simple proof-of-concept: Get liquid flowing from an input hole through a spiral to an output hole. The chip was made from three laser-cut layers: A top acrylic glass plate with the input and output wholes, a middle layer made out of double sided 3M tape that included the actual channels, and finally a bottom layer.

With Version One we improved our channel smoothness and overall build quality.
