Abstract

image

The inside cover image is a 2D pattern of water surface-tension-confined channels formed on an array of hydrophilic spots (“digits”) surrounded by hydrophobic barriers. This method, called digital liquid patterning (DLP), allows for the formation of liquid patterns of arbitrary and easily variable geometries without the need for the fabrication of new photomasks for every pattern with a different geometry. Further details can be found in article 1300075 by P. A. Levkin and co-workers.
