Research Abstract |
The aim of this study was to generate stable H_2O plasma and to evaluate its efficacy of sterilization and biomaterial compatibility. As the results of that, 1) stable generation of H_2O plasma was possible by optimization the timing of air supply and an exhaust gas and application of ultra low-volume mass flow controller (0.02 g/min). 2) H_2O plasma showed high sterilization effect to kill 10^6 G. stearothermophilus spores wrapped with tyvec^R at 60oC in 10 min. 3) porus metal disc treated with H_2O plasma cleared standard cell compatibility.
