Summary, in English

We have created devices that are extremely simple to fabricate, function without pumps, are reusable and capable of dealing with very large differences in particle sizes without clogging. Our new approach to microfluidic particle sorting is precise enough for applications in blood fractionation, cancer cell sorting, parasite detection and sample decomplexing in general. We achieve this using Deterministic Lateral Displacement (DLD) in an open channel where particles flow across a patterned surface under the impetus of capillary forces alone.
