CLSM images of the plasma treated biofilms.

Abstract

<p>3D rendered confocal laser scanning micrographs of 3-day <i>P. aeruginosa</i> biofilms, grown on polycarbonate coupons, exposed to the 20 kHz plasma jet for 0s (A and D), 60 s (B and E), and 240 s (C and F). Green colour indicates surviving cells whereas red colour indicates dead cells. Magnification power is 200x (a-c) and 600x (d–f).</p
