Figure Lengend Snippet: Monolayer GO supported TEM grids for negative staining imaging: ( a ) TEM image shows that the entire grid square is covered with a fine monolayer of GO. ( b , c ) Magnified view of each grid square. Arrows point at the near-transparent GO monolayer. A folded structure has been marked to represent complete coverage of the square. ( d – f ) Dispersion of various protein samples on GO fabricated TEM grids, observed at 80 K magnification. Arrowheads indicate each protein particle–MdtB ( d ), E. coli 70S Ribosome ( e ), VCC ( f ). ( g – i ) shows the same sample on carbon coated TEM grids (as control). ( g ) MdtB ( h ) E. coli 70S Ribosome and ( i ) VCC on carbon. GO coated TEM grids ( d – f ) attracts more biological samples.
Article Snippet: Three different biological samples, E. coli 70S Ribosome (NEB P0763S), Vibrio cholerae Cytolysin and MdtB from E. coli were visualized using this GO-coated grids.
