I need to get the TEM measurement for 2 samples Fe3O4 silica nanoparticles d only silica nanoparticles, but I am confused whether l should use carbon coated copper grids or uncoated copper grids... So kindly help me with this. ..

Dear Geetha,
how you can use uncoated grid? Your nanoparticles can´t levitate in grid hole space. You need carbon layer as a support film on grids for your nanoparticles. Just consider the thickness of carbon film. If you have very tiny nanoparticles (few nanometers) I recommend to you ultra-thin carbon film.

Hii,
In recommendation to Girman Sir,
Uncoated grid would be a bad idea, prefer carbon coated copper grids for your samples.
