A method for making a dielectric film includes a substrate on which is deposited a siloxane starting material and particles, wherein the siloxane starting material has a siloxane polymer, a siloxane oligomer and/or silane monomers, and wherein the particles have an average particle size of less than 400 nm. After deposition, heat and/or electromagnetic energy is applied to the siloxane particle layer so as to cure the layer and form a dielectric film on the substrate. The formed film is optically transmissive to visible light and transmits at least 80% of the visible light incident thereon, and is electrically insulating and has a sheet resistance of 1000 /sq or more.

A method of preventing or treating an oral disease by reducing adhesion of microorganisms, e.g. Candida albicans, to dental appliances fabricated and/or repaired by an autopolymerizing acrylic reinforcement resin comprising zirconium dioxide nanoparticles.

Compositions for rendering a hydrophobic surface hydrophilic and methods for applying them to objects such as contact lenses. A hydrophobic binder, typically a silicone compound such as a siloxane, selectively attaches hydrophilic solution-produced nanoparticles to the surface, such as hydrophobic regions of a silicone contact lens. Hydrophilic regions are preferably unmodified. The binder attaches to the particles via functional groups in solution and can autoadhere to the hydrophobic surface. A coating of the composition can be deposited from solution at ambient or room temperature, allowing coating of temperature sensitive substrates. Such coatings can withstand heating (such as for sterilization) in acidic solutions or heat sensitive solutions, retaining their hydrophilic properties.
