Figure 5

Normalized change in contact angle (Δθ/θNTC = θinitial/θNTC,initial − θ/θNTC) with varying concentrations from 0 to 103 CFU/μL in 5% whole blood at 30 min, 15 min, 10 min, and 5 min. Averages of three different experiments. Error bars represent standard errors. *Indicates substantial changes from the initial contact angles with 95% confidence.
