Modification of surface properties of microfluidic devices
Compositions, devices, and methods are disclosed for the modification of polymer surfaces with coatings having a dispersion of silicone polymer and hydrophobic silica. The surface coatings provide the polymer surface with high hydrophobicity, as well as increased resistance to biofouling with proteinaceous material. The polymer surfaces can be particularly useful in microfluidic devices and methods that involve the contacting of the covalently modified polymer surfaces with emulsions of aqueous droplets containing biological macromolecules within an oil carrier phase.

SILOXANE PLASMA POLYMERS FOR SHEET BONDING
Described herein are glass articles and methods of making glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier or bonded together using a coating layer, which is preferably an organosiloxane polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on the thin sheet, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The coating layer bonds the thin sheet and carrier together to prevent a permanent bond at high temperature processing while at the same time maintaining a sufficient bond to prevent delamination during high temperature processing.
