Cyclopropylamine plasma polymers for increased cell adhesion and growth

Plasma Processes and Polymers 14 (2017) e1600123

Plasma polymers with NHx groups were deposited from cyclopropylamine in low pressure radio frequency (RF) discharges. The amount of NHx decreased with increasing average power Pav , whereas the layer dissolution in water decreased and high Pav led to a slight film swelling. The C2C12 cells demonstrated very high adhesion to the layers regardless of the deposition conditions. Although the surface chemistry of amine-rich layers should enhance the cell proliferation, the WST-1 assay, and immunocytochemistry revealed lower cell proliferation and viability on the layers exhibiting above 18% of relative thickness loss in water. Promising results were obtained on the layers with better water stability and bearing 7–10% of NHx.
