A) Cell death quantification by counting colony forming units (CFU) for detached bacteria biofilms from HA discs coated with all AAMPs. Control group is 32% phosphoric acid-etched non-coated HA discs. N = 3. B) Merged live (green) and dead (red) bacteria viability assay images of 48-hour plaque biofilms grown on HA discs with (bottom image) and without (top image) D-GL13K coatings. C) Live and dead viability assay images of 48-hour (left), 5-day (middle), and 15-day-old (right) plaque biofilms grown on HA discs with (bottom images) and without (top images) D-GL13K coating. Middle panel shows regrown biofilms for 5 days after 45 min of ultrasonication (mechanically challenged D-GL13K coating). Right panel shows regrown biofilms for 15 days after 45 min immersion in 30% acetic acid (chemically challenged D-GL13K coating). Merged images are on the left side of each group and separated live (top)/dead (bottom) bacteria images are on the right side of each group.
