Polydimethylsiloxane (PDMS), 5 wt.% GNP/PDMS (GNP/PDMS), 1 wt.% graphene oxide (GO)/PDMS (GO1/PDMS), 3 wt.% GO/PDMS (GO3/PDMS), 5 wt.% GO/PDMS (GO5/PDMS)) were analyzed regarding hydrophobicity and roughness. Staphylococcus aureus and Pseudomonas aeruginosa biofilms were developed on these different surfaces under static conditions for 24h at 37°C. The number of biofilm total and culturable cells was quantified by flow cytometry and plate counts, respectively, whereas the biofilm amount was determined by crystal violet staining. Moreover, the mechanisms of action of GO were characterized using the flow cytometer.
