Bioinactive semi-interpenetrating network gel layers: zwitterionic polymer chains incorporated in a cross-linked polymer brush

Abstract

A thin gel layer with thermo-responsive polymer brushes and semi-interpenetrating PCMB exhibited the switching of bio-inert properties depending on temperature.

Characterization of the Hydration Process of Phospholipid-Mimetic Polymers Using Air-Injection-Mediated Liquid Exclusion Methods

“…The incident light angle was 70°, and the spot radius of light was about 2 mm. The thickness of the polymer sample layers was estimated using the software equipped with the instrument based on the previous report . Briefly, the least-squares analysis of the sample thicknesses was assumed by a refractive index according to Cauchy’s dispersion equation, as mentioned below.…”

“…The thickness of the polymer sample layers was estimated using the software equipped with the instrument based on the previous report. 15 Briefly, the least-squares analysis of the sample thicknesses was assumed by a refractive index according to Cauchy's dispersion equation, 16 as mentioned below. The fitting was carried out using the following parameters: n 0 = 1.47, n 1 = 10 000, and n 2 and thickness as unknown, so that the refractive index (n) was 1.49 (polymethacrylate resin) at 633 nm.…”

Fabrication of substrates for multiple cell patterning using a copolymer with a UV-degradable oligoethylene glycol side chain

“…Cross-linking between the unreacted silane coupling groups could also be inferred. 20 Moreover, the average contact angles of the surfaces modified with 95H and 95L (P(MEGAm95- r -MPTMS5) of high and low molecular weight) were relatively low, and the standard deviations of these data were significantly large compared with those with 85H and 90H. This point was considered based on the results of X-ray photoelectron spectroscopy (XPS) and ellipsometry measurements as described in the section “Measuring the thickness of the substrate surface by ellipsometry”.…”

Generating Surface-Anchored Zwitterionic Networks and Studying Their Resistance to Bovine Serum Albumin Adsorption

“…While numerous efforts have been disclosed to synthesize zwitterionic polymer coatings, ,,− ,− one major limitation in applying those structures requires specialty polymers (i.e., bearing various functional units) or specific coating conditions (i.e., grafting-from polymerization). In this work, we present a generic method to prepare substrate-anchored polymer coatings that feature substrate-grafted zwitterionic copolymer films, which are cross-linked via benzophenone (BP).…”
