Showcasing research from the Biological Inorganic Chemistry Laboratory (Professor Sotiris K. Hadjikakou), of the Department of Chemistry in the University of Ioannina, Greece. Hydrogels containing water soluble conjugates of silver(I) ions with amino acids, metabolites or natural products for

non infectious contact lenses The poor handling and hygiene practices of contact lenses are the key reasons for the frequent contamination of them, which is responsible for developing ocular complications.  Thus, for the development of biomaterials, combined to antimicrobial agents for contact lenses the water-soluble silver(I) covalent polymers of Glycine (GlyH), Urea (U) and the Salicylic acid (SalH2) were dispersed in polymeric hydrogels using, hydroxyethyl-methacrylate (HEMA) to form the biomaterials pHEMA@AGGLY-2, pHEMA@AGU-2, and pHEMA@AGSAL-2.
