Figure 2.
Three-dimensional structure of biofilms stained by live/dead viability staining kit. Green fluorescence indicates viable cells, whereas red fluorescence indicates dead cells. The images were three-dimensionally reconstructed using the Imaris software (Bitplane, http://www.bitplane.com) based on CLSM data at approximately 0.5 μm increments. MB: microbubble treatment without ultrasound, US: ultrasonic treatment. White arrows indicate the more gathered dead cells around the craters.
