Ammonia Sensing Behaviors of TiO2-PANI/PA6 Composite Nanofibers

Titanium dioxide-polyaniline/polyamide 6 (TiO(2)-PANI/PA6) composite nanofibers were prepared by in situ polymerization of aniline in the presence of PA6 nanofibers and a sputtering-deposition process with a high purity titanium sputtering target. TiO(2)-PANI/PA6 composite nanofibers and PANI/PA6 composite nanofibers were fabricated for ammonia gas sensing. The ammonia sensing behaviors of the ...

Assessing Cellular Response to Functionalized α-Helical Peptide Hydrogels

α-Helical peptide hydrogels are decorated with a cell-binding peptide motif (RGDS), which is shown to promote adhesion, proliferation, and differentiation of PC12 cells. Gel structure and integrity are maintained after functionalization. This opens possibilities for the bottom-up design and engineering of complex functional scaffolds for 2D and 3D cell cultures.

Spontaneous Helical Structure Formation in Laminin Nanofibers.

Laminin is a cross-shaped heterotrimer composed of three polypeptides chains that assembles into an insoluble extracellular matrix (ECM) network as part of the basement membrane, serving a vital role in many processes such as embryonic development, differentiation, and muscle and nerve regeneration. Here we engineered monodisperse laminin nanofibers using a surface-initiated assembly technique ...

Electrospun TiO2 nanofibers for gas sensing applications

Nanostructured TiO2 has attracted much attention for a variety of applications including photocatalysts, electrodes for water photolysis, dye-sensitized solar cells, and gas sensors. In this work we report on TiO2 fiber mats for use in gas sensors demonstrating exceptionally high sensitivity to NO2, a toxic gas responsible for acid rain and other air pollution effects, and high sensitivity to H...
