Figure Lengend Snippet: SEM-EDXA and TEM analysis of AuNPs synthesized by Deinococcus radiodurans . Notes: ( A and B ) SEM images of AuNPs-loaded D. radiodurans cells with 1 mM Au(III) and 5 mM Au(III), respectively. ( C ) EDX spectra of AuNPs-loaded D. radiodurans cells. ( D ) SEM image of purified AuNPs synthesized by D. radiodurans with 1 mM Au(III). ( E ) TEM image of AuNPs-loaded D. radiodurans cells. Arrows in A and B indicate the AuNPs on cell surface. Arrows in D indicate different morphologies and sizes of the purified AuNPs. Arrows in E indicate the AuNPs distributed on the cell envelope, across the cytosol as well as in the extracellular space. Scale bars in the pictures indicate the corresponding length. Abbreviations: SEM, scanning electron microscopy; EDXA, energy-dispersive X-ray analysis; TEM, transmission electron microscopy; AuNPs, gold nanoparticles; EDX, energy-dispersive spectroscopy; D. radiodurans , Deinococcus radiodurans .
