The invention provide a new lens curing method for making hydrogel contact lenses. The new lens curing method is based on actinically-induced step-growth polymerization. The invention also provides hydrogel contact lenses prepared from the method of the invention and fluid compositions for making hydrogel contact lenses based on the new lens curing method. In addition, the invention provide prepolymers capable of undergoing actinically-induced step-growth polymerization to form hydrogel contact lenses.
Glucose-sensing luminescent dyes, polymers, and sensors are provided. Additionally, systems including the sensors and methods of using these sensors and systems are provided.
The present invention relates to a complex comprising a cationic block copolymer and a nucleic acid, the cationic block copolymer having at least a tri-block structure comprising a cationic block and two hydrophilic blocks, or a hydrophilic block and two cationic blocks.
