Capillary-force, Self-filling Bi-laminating Mixing

Capillary-force, Self-filling Bi-laminating Mixing 

Capillary forces are a suitable means for manual self-filling of samples into minute channel cavities [111], However, this usually allows one to fill in only one liquid. Therefore, a specially technique had to be developed which allows the filling of two liquids, based on a self-closing and self-re-opening mechanism.

The device actually made contained seven pairs of such adjacent channels with a small gap, placed in parallel in a quadratic format [111]. 

It can be envisaged that, facing the target application in environmental and medical analysis, cleaning can be done by solvents or hot vapor [111]. Alternatively, disposable materials may be employed so that the device can be used as once-only tool. For medical analysis, the integration of a needle may be advisable.
