Abstract
The feasibility of time‐controlled and reversible drug delivery to Caenorhabditis elegans (C. elegans) embryos immobilized on‐chip is demonstrated by regulated blocking of cytokinesis using Cytochalasin‐D. In article https://doi.org/10.1002/advs.201700751 by Martin A. M. Gijs and co‐workers, the implementation of versatile microfluidic protocols, including time‐controlled and reversible drug delivery to on‐chip, immobilized embryos, demonstrates the potential of the reported device for biochemical and pharmacological assays.
