In this study, silicone hand was disinfected by homemade touchable non-thermal plasma to simulate and evaluate its feasibility of application on human hand. Experimental results showed that there was no significant difference whenEscherichia coli (E. coli),Staphylococcus aureus (S. au),Staphylococcus albus (S. al), andPseudomonas aeruginosa (P. ae) were loaded on the silicone hand surface and treated with plasma. The efficiency of plasma disinfection was higher when the treatment time was prolonged or initial bacterial density was lower. When initial bacterial number was 1.0×106–1.0×107 CFU, the plasma disinfection process mainly occured in the first 5 s and more than 99% of bacteria could be disinfected. This study can provide guidelines for the development of a new plasma device for human hand disinfection.
