Abstract: A surface-treated fluidic channel is provided comprising a dispensing device that comprises a microarray of microchannels. The fluidic channel is made from metal and comprises a surface and a hydrophobic coating layer comprising a self-assembled monolayer of an organophosphorus acid adhered to the surface. A mesh nebulizer comprising a reservoir and a dispensing device comprising a microarray of microchannels is also provided. A metal surface layer is applied to the interior and exterior surfaces of the reservoir and dispensing device, and a hydrophobic coating layer comprising an organo-silicon or a self-assembled monolayer of an organophosphorus acid is adhered to the metal surface layer, usually on the exterior surfaces of the reservoir and dispensing device. A hydrophilic polymeric coating layer may be chemically bonded to and propagated from terminal functional groups on the hydrophobic coating layer on the interior surfaces of the reservoir and dispensing device.

Abstract: Methods of altering the surface energy of components of a mesh nebulizer are provided, comprising: a) depositing a metal surface layer on surfaces of the component; b) forming a hydrophobic coating layer comprising an organo-silicon or a self-assembled monolayer of an organophosphorus acid directly on the metal surface layer or indirectly on the metal surface layer through an intermediate organometallic coating; and either: i) removing select areas of the hydrophobic coating layer to expose the metal surface layer; or ii) forming a polymeric coating layer chemically bonded to and propagated from terminal functional groups on the hydrophobic coating layer that are capable of initiating polymer growth when exposed to a source of polymerizable monomer, on select areas of the components. Mesh nebulizers formed by such methods are also provided.

Abstract: A method of manufacturing a printed circuit board is providedd, comprising: 1) imprinting an electrically conductive circuit pattern on a surface of a substrate; 2) applying a surface treatment composition to the surface of the substrate over the electrically conductive circuit pattern; and 3) allowing the surface treatment composition to form a self-assembled coating layer on the surface of the substrate in the form of a conformal coating.
