Nanopatterned (330 nm wide channels) type I collagen films were prepared by solvent casting on poly(dimethyl siloxane) (PDMS) templates. These films were rolled into tubular constructs and crosslinked. Tubular constructs were incubated under cell culture conditions for 28 days and examined by stereomicroscopy and scanning electron microscopy (SEM) for the integrity of the structure. The nanopatterned films were also seeded with human vascular smooth muscle cells (VSMCs) and examined after immunostaining with fluorescence microscopy and SEM to assess the cell phenotype and alignment on the nanopatterns on the films.

Free standing layer-by-layer films of polyethyleneimine and poly(l-lysine) for potential use in corneal stroma engineering
Altay, Gizem; Hasırcı, Vasıf Nejat; Khademhosseini, Ali; Department of Biomedical Engineering (2011)
In this study we fabricated free standing multilayer films of polyelectrolyte complexes for potential use in tissue engineering of corneal stroma by using the layer-by-layer (LbL) approach. In the formation of these LbL films negatively charged, photocrosslinkable (methacrylated) hyaluronic acid (MA-HA) was used along with polycations polyethyleneimine (PEI) and poly(L-lysine) (PLL). Type I collagen (Col) was blended in with PLL for improving the water absorption and cell attachment properties of the films....
Photopatterning of PMMA Films with Gold Nanoparticles: Diffusion of AuCl4- Ions
Yilmaz, Eda; Ertaş, Gülay; Bengu, Erman; Suzer, Sefik (2010-11-04)
Photopatterning of poly(methyl methacrylate) (PMMA) films is performed by UV irradiation of the polymer films containing uniformly distributed AuCl4- ions. The process reduces the gold ions and leads to production of Au nanoparticles in the irradiated regions at room temperature (RT). Resulting films are investigated with scanning electron microscopy, which revealed, in addition to regions with gold nanoparticles, the presence of "ion-depleted regions". These regions are formed at RI and within the rigid po...
Ionic conductivity of microporous titanosilicate ETS-10 and ion-exchanged Mn+-ETS-10 (where, Mn+ = Li+, Na+, Mg2+, Zn2+, Ca2+) thin films prepared by secondary growth method
Galioglu, Sezin; Çam, İbrahim; Akata Kurç, Burcu (2017-09-15)
Impedance spectroscopy was used to investigate the long-range ionic conductivity of the microporous, titanosilicate (Na,K)-ETS-10 and ion-exchanged Mn+-ETS-10 (where, Mn+ = Li+, Na+, Mg2+, Zn2+, Ca2+) thin films prepared by secondary growth method. To figure out the effect of grain boundary on ionic conduction, as-synthesized (Na,K)-ETS-10 films possessing different thicknesses of columnar grain structure (i.e., films prepared via 4h-, 6h-, 8h-, and 10h-growth) were tested. The conductivities of the films w...
Micropatterned lead zirconium titanate thin films
Vartuli, JS; Özenbaş, Ahmet Macit; Chun, CM; Trau, M; Aksay, IA (Cambridge University Press (CUP), 2003-05-01)
Micropatterning of Pb(Zr0.52Ti0.48)O-3 (PZT) thin films with line features as small as 350 nm was demonstrated through capillary molding of organometallic solutions within the continuous channels of an elastomeric mold. Despite the large stresses that develop during the evaporation of the solvent, pyrolysis of the organics, and the densification and crystallization of the inorganic gel, the patterned crystalline PZT films were crack-free and mechanically robust. Flawless regions as large as I cm(2) were obt...
Immobilization of Invertase in a Novel Proton Conducting Poly(vinylphosphonic acid) - poly(1-vinylimidazole) Network
Isikli, Suheda; Tuncagil, Sevinc; Bozkurt, Ayhan; Toppare, Levent Kamil (Informa UK Limited, 2010-01-01)
A novel proton conducting polymer blend was prepared by mixing poly(vinylphosphonic acid) (PVPA) with poly(1-vinylimidazole) (PVI) at various stoichiometric ratios via changing molar ratio of monomer repeating unit to achieve the highest protonation. The polymer network having the most suitable stoichiometric ratio for substantial proton conductivity was prepared and characterized by FT-IR spectroscopy and proton conductivity measurements. The network was used for immobilization of invertase and some import...
