Preparation of a Molecularly Imprinted Soft Contact Lens as a New Ocular Drug Delivery System for Dorzolamide

In the present work a series of imprinted (MIPs) and non-imprinted (NIPs) hydrogels were prepared using 2-hydroxyethyl methacrylate (HEMA) as a backbone monomer, ethylene glycol dimethacrylate (EGDMA) as a cross-linker monomer, methacrylic acid (MAA) as a functional monomer and dorzolamide (DZD) as the template molecule. Different concentrations of MAA (0, 100, 200, 400 mM) were used for preparation of NIPs. Two DZD: MAA molar ratios (1:8 and...
