can some body email me a standard golden nanoparticle image please
In addition to the other advice already given:
1) Reduce the physical size of your sample as small as possible. More mass = more thermal vibrations.
2) Reduce the temperature of your sample (and room) as much as feasible and comfortably possible.
3) Dont place your AFM on a table. It should be mounted on a heavy slab which is in turn suspended by a system of springs, much like a DJ spinning board for techno music. If you dont have such a setup, use the heaviest table you can find.
4) If possible, use an adhesive to attach your sample to a holding chip, but use as little adhesive as possible. Allow at least 24 hours after affixing with the adhesive before imaging, to relieve tension.
5) If possible, load the AFM, focus, and then allow it to sit for several hours (or an entire day) in order to come to total thermal equilibrium and reduce thermal drift and vibrations.
Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.
There is only one important assumption: you have to be interested in nano!
Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
