Treating E. coli and B. subtilis with ZnMgO nanoparticles. TEM images of Gram-negative bacteria E. coli (blue) and Gram-positive bacteria B. subtilis (rose) treated with mixed ZnMgO nanoparticles. Note nanoparticles association with bacterial cells, the leakage of cell content and particles aggregations in the bacterial grown medium. Images were obtained at MIMA2 MET platform in INRA Jouy en Josas. Bar 1000 nm
