Figure 9

Number of adherent monocytes per mm2 on AuNP, Au, TCP, and Thx after 18 hours of primary adhesion followed by 24 hours of culture and a 1 hour challenge with either opsonized zymosan particles or opsonized Staphylococcus epidermidis. Unstimulated cells were used as controls.

Notes: Data represent the mean ± standard deviation (n=4–6). Significant differences between treatments are indicated by letters a–c, where bars that share the same letters are significantly different (P<0.05).

Abbreviations: Au, smooth gold surface; AuNP, nanostructured gold surface; TCP, tissue culture-treated polystyrene; Thx, tissue culture-treated plastic cover slip.
