Antimicrobial activity of the AgNP gel determined by the well diffusion method. The AgNP gel (S1 [yellow], S2 [orange], S3 [red]), povidone iodine and control gel were dropped into wells and incubated with pathogens for 24 h at 37 °C. The inhibition zones were measured in mm in diameter. (a) E. coli, (b) S. aureus, (c) P. aeruginosa, (d–h) S. pseudintermedius MIC 407, 408, 411, 504, 509, respectively.
