Length dependent inflammatory response to AgNW in the lungs at 24 hour. C57/Bl6 mice were exposed to AgNW and control panel by pharyngeal aspiration. At 24 hour post exposure the lungs were lavaged and total cell number (A) and total granulocyte number (B) were measured. C) The acute inflammatory increase was plotted against length of AgNW. Significance indicated compares treatment groups to vehicle control (B) and within each treatment (C), * indicates p < 0.05, ** indicates p < 0.001. Data represent mean ± SEM of n = 4 mice.
