Figure 4

Antibacterial activity of matrix-embedded nano-coatings (on wood) (a,b) towards E. coli (a) and S. aureus (b); comparison of antibacterial effect of matrix-embedded nano-coatings (on wood) during 1 h and bare NPs on glass surfaces during 15 min (c,d) towards E. coli (c) and S. aureus (d). Photocatalytic dye degradation (e) is shown to illustrate differences in photocatalytic efficiency of the studied surfaces. Mean value from 3 experiments ±SD is presented. Red dotted line denotes the practical limit of quantification with 3 colonies counted in undiluted samples.
