Synthesis and characteristics of the poly(carboxybetaine)s and the corresponding cationic polymers

Dual-Functional Biomimetic Materials: Nonfouling Poly(carboxybetaine) with Active Functional Groups for Protein Immobilization

“…The thickness of the polymer layer was around 10−15 nm, as measured by ellipsometry. Protein adsorption was measured with a custom-built SPR sensor based on wavelength interrogation . Protein adsorption is defined as the wavelength shift before protein injection and after buffer wash.…”

“…Protein adsorption was measured with a custombuilt SPR sensor based on wavelength interrogation. 22 Protein adsorption is defined as the wavelength shift before protein injection and after buffer wash. The wavelength shift after protein injection is mainly due to the change in the bulk refractive index.…”

“…Yield: 91%. NMR was recorded on a Bruker spectrometer using deuterated water as a solvent: 1H NMR (300 MHz): 6.06 (s, 1H, CH), 5.68(s, 1H, CH), 4.55 (t, 2H, OCH 2 ), 3.70 (t, 2H, CH 2 N), 3.59 (t, 2H, NCH 2 ), 3.10 (s, 6H, NCH 3 ), 2.64(t, 2H, CH 2 COO), 1.84 (s, 3H, CCH 3 ). 13C NMR (500 MHz): 180.27(COO - ), 172.43 (COO), 139.16, 131.77, 66.38, 66.31, 62.44, 55.35, 34.76, 21.30.…”

“…Yield: 91%. NMR was recorded on a Bruker spectrometer using deuterated water as a solvent: 22 Surface-Initiated Polymerization on Surface Plasmon Resonance (SPR) Sensors. Electron beam evaporation under vacuum was used to coat glass chips with a layer of chromium (2 nm thick) to promote the adhesion of a subsequent surface plasmon active layer of gold layer (48 nm thick).…”

Partitioning of unsaturated hydrophilic monomer in microemulsion media monitored by pyrene fluorescence method

“…The monomers, DMAPS, trimethyl (methacryloyloxyethyl)ammonium methylsulfate (TMMEAMS), and poly(DMAPS) were prepared as described previously (Chart ) 15–19…”
