Figure 9

Antibacterial activity of (a) PLA/Ag/PEG (rec-01), (b) PLA/Ag/PEG (rec-02), (c) PLA/Ag/PVP (rec-03) and (d) PLA/Ag/PVP (rec-04) 3D printed PLA/AgNP nanocomposites with 100 µm 3D printed layer thickness, against S. aureus and E. coli after 30, 60, and 120 min of contact. Mean values do not differ significantly (p < 0.05).
