Synthesis of Collagen‐Like Sequential Polypeptides Containing O‐Phospho‐L‐Hydroxyproline and Preparation of Electrospun Composite Fibers for Possible Dental Application

“…[22,23] A calcium chloride solution (0.2 M) containing 0.01 M Tris HCl (pH ¼ 7.4) and a 0.12 M disodium hydrogen phosphate solution was prepared. An HMDItreated ESNW sample was immersed first in the CaCl 2 solution and allowed to stand for 30 min; then the ESNW sample was briefly rinsed with distilled water, followed by subsequent immersion in the Na 2 HPO 4 solution for 30 min and rinsed with distilled water.…”

“…The crystallization experiments were performed by means of so‐called alternate immersion (soaking) 22, 23. A calcium chloride solution (0.2 M ) containing 0.01 M Tris HCl (pH = 7.4) and a 0.12 M disodium hydrogen phosphate solution was prepared.…”

Thermo-responsive polymers

“…When the polymer is in the swollen state, the surface becomes hydrophilic and, on collapsing of the polymer chains the surface, becomes relatively hydrophobic, thus offering a way of thermally controlling the behavior of surfaces. The "grafting from" method uses pre-attached initiators/precursors on the surface, which are further used for polymerization from the surface and thus allow better control of grafting density of the polymer (Suzuki et al, 2000;Yakushiji et al, 1999). Thermo-responsive polymers have been grafted onto surfaces by using radiation-induced polymerization approaches such as electron beam irradiation (Akiyama, Kikuchi, Yamato, & Okano, 2004;Hirose, Kwon, Yamato, Kikuchi, & Okano, 2000), UV-induced polymerization (Sugawara & Matsuda, 1994;Von Recum et al, 1998), and plasma polymerization (Cheng et al, 2005;Pan, Wesley, Luginbuhl, Denton, & Ratner, 2001).…”

Calcium Phosphate Crystallization on Electrospun Cellulose Non‐Woven Fabrics Containing Synthetic Phosphorylated Polypeptides

“…[23,24] A 0.2 M calcium chloride solution containing 10 À2 M Tris Á HCl (pH ¼ 7.4) and a 0.12 M disodium hydrogen phosphate solution were prepared. The non-woven fabrics were first immersed in the CaCl 2 solution and allowed to stand for 30 min, then the non-woven fabrics were briefly rinsed with distilled water, followed by a subsequent immersion in the Na 2 HPO 4 solution for 30 min then rinsed with distilled water.…”
