Copolymerization of hydroxyethyl methacrylate (HEMA) with a methacrylated-derivative of β-cyclodextrin (β-CD) was evaluated as a way to obtain hydrogels with tunable mechanical and drug loading and release properties, particularly for preparing medicated soft contact lenses. A fully methacrylated β-CD monomer was synthesized and added to the HEMA and cross-linker solution at concentrations ranging...
Soft contact lenses are receiving an increasing attention not only for correcting mild ametropia but also as drug delivery devices. To provide poly(hydroxyethyl methacrylate), PHEMA, lenses with the ability to load norfloxacin (NRF) and to control its release, functional monomers were carefully chosen and then spatially ordered applying the molecular imprinting technology. Isothermal titration calorimetry...
