In addition, the substrate embedding of the Au-NG provides flexibility, a flat surface, and excellent adhesion to polymer substrates for practical applications.
The manual tracking plug-in was used to follow the migration of the cells inside the channels on flat surfaces or on adhesion mediating lines.
Furthermore, our data strongly indicate specific adhesion to flat substrates via both costameric and focal adhesions.
To this effect, we took advantage of the nontransformed mouse lung epithelial type II line, E10 that has extensive GJIC, an even and flat morphology and good adhesion to the substratum even at high densities [ 22].
Cells adhere to flat surfaces through focal adhesions, which are integrin-based contacts between the cell and the extracellular matrix [ 1- 3].
For samples with a smooth PDMS layer the transition from flat to structured state reduces adhesion by 56%, and for samples with a micropatterned PDMS layer adhesion is switchable by nearly 100%.
Analyses indicate that the pre-load and adhesion during the flat punch test play a minor role on the size effect.
The precoating of poly vinyl pyrrolidone) (PVP) on a porous alumina support was the key to providing a flat platform and improving the adhesion properties of alumina with TiO2, which allowed for the formation of om-TiO2 membranes.
All STF nanotopographies investigated in the absence of adsorbed FN were found to significantly enhance cell adhesion relative to flat substrates; and the addition of FN to STFs was found to have cell-dependent effects on enhancing cell material interactions.
