title: Micropatterning hydrophobic liquid on a porous polymer surface for long-term selective cell-repellency.
abstract: A simple method to form precise micropatterns of hydrophobic liquids using porous hydrophilic-hydrophobic substrates is presented. The micropatterns of hydrophobic liquid exhibit long-term stability, excellent cell-repellency, no cytotoxicity, and are more efficient than conventional PEG or superhydrophobic surfaces in controlling eukaryotic cell adhesion.
