The fast photochemical nanocoating process allows local formation of the nanocoating. Patterning is thus achieved in a single step, without the need for etching or other additional post-coating steps.
For many applications, local control of surface properties offers great benefits. By creating patterns of hydrophobic and hydrophilic areas, liquids can be confined on a surface. When applied in microfluidic devices, this allows the flow of liquids to be controlled and directed.
Local control of the adsorption of biomolecules or adhesion of cells also offers interesting opportunities for applications such as cell arrays and organ-on-a-chip.
