The diameters of the formed inhibition rings by the AgNPs/SS/agar films with different UV irradiation times.

	SS/Agar (cm)	UV 10 min (cm)	UV 30 min (cm)	UV 60 min (cm)
E. coil	NA	1.67 ± 0.04 a	1.69 ± 0.02 a	1.74 ± 0.05 a
S. aureus	NA	1.70 ± 0.21 a	1.81 ± 0.04 b	2.21 ± 0.04 c

NA, no inhibition ring. The superscript a, b, and c indicate that the data between the groups are statistically different. The superscript with the same letter indicates no statistical difference between the groups. p < 0.05.
