Microfluidic control

To make the reagents flow between the different sample preparation process chambers, a net of microchannels with connections, membranes, bifurcations and crossways are needed. Fluidic control devices must be designed according to the disposability nature of the designed LOC. Hence, if pumps and valves need to be used just once, they can be simplified and made from wax, hydrogels, or even frozen solvent. However, these approaches have not been applied in a commercial device yet.

Recently, there have been new approaches and results that allow us to be optimistic about the possibility of valves and pump integration [48]. The former one is based on moveable parts embedded in a sealed microchannel, and the latter one is based on the bonding of SU-8 to really elastic materials. Both concepts are in a patent filling process within the partners of the consortium.

The right balance between relevant, feasible and efficient research.
