  • Phosphorylcholine group-containing polysiloxane monomer
    Patent number: 11851516
    Abstract: Provided is a monomer suitable for application to an ophthalmic device, the monomer showing high surface hydrophilicity, a high oxygen transmissibility, and appropriate mechanical strength when copolymerized with a polymerizable monomer, such as a hydrophilic monomer. It has been recognized that a phosphorylcholine group-containing polysiloxane monomer can solve the problems.
    Type: Grant
    Filed: April 4, 2019
    Date of Patent: December 26, 2023
    Assignee: NOF CORPORATION
    Inventors: Yosuke Matsuoka, Akane Katori, Norio Iwakiri, Shu Takashima, Ryuya Gotanda, Nobuyuki Sakamoto
  • Poly(ethylene glycol) derivative and protein-adsorption inhibitor
    Patent number: 11442062
    Abstract: A compound is provided which is effectively adsorbed to a substrate surface, such as an immune reaction vessel, has extremely high protein adsorption inhibitory effect that inhibits non-specific adsorption of protein or the like, and has excellent washability to retain the inhibitory effect before and after washing operation of the substrate. Also provided are a protein adsorption inhibitor using the compound, a phosphorylcholine-modified substrate, and a method for inhibiting protein adsorption. The compound is a phosphorylcholine group-containing polyethylene glycol derivative represented by formula (1). The method for inhibiting protein adsorption of the present invention includes the step of forming an adsorbed layer of the derivative on a substrate surface.
