Pseudomonas aeruginosa PAO1 biofilms grown on borosilicate coupons were treated with
gas-discharge plasma for various exposure times. Almost 100% of the cells were inactivated
after a 5-min plasma exposure. Atomic force microscopy was used to image the biofilms and
study their micromechanical properties. Results show that the adhesiveness to borosilicate
and the thickness of the Pseudomonas biofilms are reduced upon plasma treatment.
