Size-dependent sorting of C. elegans nematodes through an adjustable microfluidic filter structure.

We introduce a new and simple microfluidic sorting device based on adjustable filter structures that can be easily tuned by external pressure for a specific size-dependent C. elegans worm sorting experiment. A single device can be used for selecting and sorting of all worm stages and single-sex populations on a microfluidic chip, in particular for sorting male and age-matched hermaphrodite C. elegans worms.
