Application

  • Supplementary Information for “Permeable Protein-Loaded Polymersome Cascade Nanoreactors by Polymerization-Induced Self-Assembly”: This study involves the use of 2-hydroxypropyl methacrylate, a mixture of isomers, as a precursor in the creation of protein-loaded nanoreactors (LD Blackman et al., 2020).
  • Shape-Shifting Thermoresponsive Block Copolymer Nano-Objects: Explores the use of hydroxybutyl methacrylate (HBMA) in the synthesis of block copolymer nano-objects, focusing on its ability to shift shapes in response to temperature changes (SJ Hunter et al., 2023).

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
