Photopolymerization-Based Fabrication of Chemical Sensing Films

Abstract
LANL researchers have invented a photopolymerization method for attaching a chemical microsensor film to an oxide surface. The method binds the polymer to the substrate using a covalent attachment and forms a highly cross-linked polymer, forming a more robust and stable sensor than currently available polymer-based sensors. The invention permits creation of patterns of different sensing elements on the same sensor and permits the use of recognition elements that bind by electric non-covalent interactions, size and, shape. This fabrication method is faster and cheaper than current methods and does not require the use of a photoinitiator.

Application(s)
This invention broadly applicable to the manufacture of chemical sensor for a variety of applications, including homeland security. The sensing film can be used in a variety of sensing platforms (surface acoustic, optical waveguide, fiber-optic, FET) and can be used vapor-phase and liquid-phase sensing.
