Depths (µm) of polymicrobial biofilm (as indicated by the presence of bacterial cells) after exposure to silver dressings for 48 hours. Dressings were tested in triplicate and five images were captured for each dressing (n = 15). ^∗ p < 0.000 compared to initial biofilm. ^† p < 0.000 compared to NCSD and SNAD.

Sample	Maximum depth (µm) [mean ± standard deviation]
Initial biofilm T 24 hours	9.75 ± 2.37
NCSD	6.22 ± 5.93∗
SNAD	4.77 ± 1.91∗
NGAD	1.99 ± 1.22∗†
