Bronchoalveolar Lavage Protein Quantification: Protein concentration measured by Bradford assay from recovered BAL Fluid following 200 μl IT instillation of citrate vehicle, 200 μg 20 nm AgNP or silver acetate (AgAc). Statistical significance p<0.05 compared to ^anaïve or ^bcitrate vehicle determined by one way ANOVA with Tukey post hoc test. n=4–5. Data reported as mean ± SEM.

	Total Protein (mg/ml)
Naive	0.15 ± 0.01
Citrate Vehicle
1 d	0.31 ± 0.09
7 d	0.22 ± 0.02
AgNP
1 d	0.33 ± 0.02
7 d	0.18 ± 0.03
AgAc	3.88 ± 2.25

Note: Protein concentration measured by Bradford assay from recovered BAL fluid. Silver nanoparticle (AgNP) or silver acetate (AgAc) was deliverd as a 200 μg in 200 μl installation blous. Statistical significance p<0.05 compared to naïve or Citrate vehicle determined by one way ANOVA with Tukey post hoc test. n=4–5. Data displayed as mean ± SEM.
