Nanolitre liquid patterning in aqueous environments for spatially defined reagent delivery to mammalian cells

Biopatterning, which enables regulation of cell–material interaction, is usually achieved by techniques that rely on physical contact, which can seriously damage cells. A simple and efficient non-contact technique is now demonstrated using an aqueous two-phase polymer system.
