Abstract:
This invention provides high unit density arrays of microparticles and methods of assembling such arrays. The microparticles in the arrays may be functionalized with chemical or biological entities specific to a given target analyte. The high unit density arrays of this invention are formed on chips which may be combined to form multichip arrays according to the methods described herein. The chips and/or multichip arrays of this invention are useful for chemical and biological assays.
Abstract:
Silicone hydrogel contact lenses having ophthalmically acceptable surface wettabilities are obtained from pre-extracted polymerized silicone hydrogel contact lens products produced from a polymerizable composition comprising a combination of particular components. The silicone hydrogel contact lenses can be obtained from non-polar resin based contact lens molds and without surface treatments or an interpenetrating polymeric network of a polymeric wetting agent. Related lens products, polymerizable compositions, and methods are also described.
Abstract:
Silicone hydrogel contact lenses are formed from the reaction product of a polymerizable composition comprising at least one hydrophilic vinyl amide-containing monomer, at least one acrylate-containing siloxane monomer, and at least one hydrophilic vinyl ether-containing monomer. The contact lenses have ophthalmically-acceptable surface wettability and can be manufactured without the use of volatile organic solvents.
Abstract:
Silicone hydrogel contact lenses that have good dimensional stability, are ophthalmically-acceptable, and can be manufactured without the use of alcohol solvents are formed from the reaction product of a polymerizable composition comprising at least one mono-functional acrylate-containing siloxane monomer having a molecular weight of less than 2,000; at least one bi-functional acrylate-containing siloxane monomer having a molecular weight of at least 3,000; and at least one hydrophilic vinyl-containing monomer, wherein the polymerizable composition has a molar ratio of total amount of mono-functional acrylate-containing siloxane monomer to total amount of bi-functional acrylate-containing siloxane monomer of at least 30:1, respectively.
Abstract:
Silicone hydrogel contact lenses are produced without using volatile organic solvents to extract materials from the polymerized contact lens bodies, and instead are washed with aqueous liquids. The silicone hydrogel contact lenses so produced have ophthalmically wettable lens surfaces such that less than five percent of a batch of twenty or more such silicone hydrogel contact lenses have visually identifiable non-wetting spots when the contact lenses are located on eyes of subjects.
Abstract:
Silicone hydrogel contact lenses having a high water content are described. The lenses are derived from a polymerizable composition including a first siloxane monomer represented by formula (1): wherein m of formula (1) represents one integer from 3 to 10, n of formula (1) represents one integer from 1 to 10, R1 of formula (1) is an alkyl group having from 1 to 4 carbon atoms, and each R2 of formula (1) is independently either a hydrogen atom or a methyl group; the lenses also include units derived from a second siloxane monomer having a number average molecular weight of at least 7,000 daltons, and at least one vinyl-containing cross-linking agent. The lenses have average equilibrium water contents from about 30% wt/wt to about 70% wt/wt when fully hydrated. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
