We investigated the effect of arrayed nanostructures on the cell adhesion rate by forming nanopillars on a PMMA polymer surface, and demonstrated cell patterning tools for the polymer surface without biological or chemical reagents. Nanopillar arrayed structures with various heights (0, 50, 100, 150, and 200nm with 50nm of pitch size and 60nm of diameter) were formed on a PMMA surface by using nano-molding...
We developed a simple and reproducible epithelial cell-patterning tool on a PDMS (polydimethylsiloxane) polymer surface using a micro plasma structure that did not require chemical or biological treatment. The concept behind this novel approach was based on the fact that cells should easily adhere to the plasma-treated PDMS surface and not the inherent PDMS surface. The micro plasma structure consisted...
