Biofilm-resistant performance of Ti-Ga alloy. (A) SEM images of biofilm formed by S. aureus and E. coli after different treatments. (B) Confocal 3D images of biofilm of S. aureus and E. coli. (C) Representative images of bacterial colonies from biofilms on the surfaces of alloys. (D) Relative amounts of S. aureus and E. coli biofilm biomass. (E) Biofilms treated with different groups of alloys for 24 h and stained with 1% crystal violet. (F) Quantification of biofilm formation of S. aureus and E. coli by using a microtiter plate reader
