Description
Summary:Atmospheric pressure plasma jet (APPJ) was used as an alternative approach to conventional low-pressure plasma irradiation in fabricating the bio-compatible material surfaces for cell culture 1 . Polydimethylsiloxane (PDMS) surfaces were irradiated to the double electrode APPJ with grounded additional pin electrode at the bottom of the treated surface 2 . The contact angle was used as the indicator to identify the hydrophilicity of the treated surfaces. The sessile method was performed by placing using 2\ \ \mu \mathrm{L} water droplet on the irradiated surfaces 1 . Water droplets were photographed to estimate the contact angle using the ImageJ software. Parameters of capillary tube inner diameter, irradiation time, and relaxation time after the irradiation were considered to evaluate the hydrophilicity changes on the treated PDMS surfaces. Fabricated PDMS surfaces were used for cell culture using the mouse osteoblast cells (MC3T3-E1) after 30 minutes from the irradiation as treated surface shows stable relaxation in the period of 30 minutes - 1 hour.
