Direct-Contact Low-Frequency Ultrasound and Pulse Lavage Eradicates Biofilms on Implant Materials In Vitro

Figure 2

Confocal laser scanning microscopic images showing S. aureus of control, pulse lavage (PL), and direct-contact low-frequency ultrasound (DCLFU) treatment groups. Live cells are stained green (appears bright in grayscale) and dead cells are strained red (appears dim in grayscale). The scale bar represents 100 μm magnification.
