SEM images of four kinds of bacteria with and without anti-treatments. a P. aeruginosa positive control and treated with 200 μg/ml of 3 % Ta-ZnO by MIC under dark ambient and with 160 μg/ml of 1 % Ta-ZnO under visible light for 10 min. b E. coli positive control and treated with 300 μg/ml of 3 % Ta-ZnO by MIC under dark ambient and with 160 μg/ml of 1 % Ta-ZnO under visible light for 10 min. c S. aureus positive control and treated with 200 μg/ml of 1 % Ta-ZnO by MIC under dark ambient and with 160 μg/ml of 1 % Ta-ZnO under visible light for 10 min. d B. subtilis positive control and treated with 160 μg/ml of 1 % Ta-ZnO by MIC under dark ambient and with 160 μg/ml of 1 % Ta-ZnO under visible light for 10 min
