[Analysis Case] Investigation of the Causes of Wettability Changes Due to Plasma Treatment
Evaluation of the top surface of modified layers of polymers, resins, and films using TOF-SIMS is possible.
On the surface of cell culture dishes, treatments are performed to convert hydrophobic plastic surfaces to hydrophilic ones in order to enhance cell adhesion. In this study, the surfaces of dishes that underwent hydrophilic treatment were evaluated using XPS and TOF-SIMS, revealing an increase in OH and CHO groups. By conducting quantitative evaluations with XPS and qualitative evaluations with TOF-SIMS, it is possible to capture how the surface has changed.
