Microfluidic devices can be manufactured from a wide variety of material depending on the end purpose of the device.
Often referred to as “Lab on a Chip” devices they can be used for a variety of processes including transport, separation, mixing or indeed act as reaction vessels. Such devices can be used in a variety of applications including cellular and bacterial processes, fuel cells, optofluidics, reaction chemistry etc.
Microfluidic devices typically have structures that are composed of channels and wells, which can be combined to act as micro pumps etc for fluid mixing. Channels have dimensions that are typically < 100 microns wide and 100 microns deep.
These devices can be made form a host of materials including glasses e.g. borosilicate, polymers e.g. PMMA etc.
Direct laser ablation can produce a variety of shapes, see example images, of serpentine channels and wells which can be combined to produced complex structures. In addition, holes in the substrate can be created to allow the introduction of reagents.
