Abstract
Devices and methods for immobilizing micrometer sized liquid domains onto a chemically functionalized substrate surface are disclosed. A multifunctional polymer is adsorbed at the surface interface of the liquid microdomains, and the liquid microdomains are immobilized by covalent bonding or non-covalent forces such as electrostatic attraction between the adsorbed multifunctional polymer and the functionalized substrate surface.
