[Spm] Preparing Nanotubes for AFM-imaging

[Uwe Mick]

Dear colleagues,

first of all: have a good and successfull 2009!!! ;)

I want to image multiwall-nanotubes with AFM and SEM.

Could anybody provide me with some tips or references on how to prepare good Nanotube-samples for imaging with an AFM?
I have MWCNTs as a dry poder and want to disperse them onto a conductive sample (preferably silicon) so that they can be imaged by AFM and SEM.

What sovents, additives or emulsifying agents (and methods of deposition) would best be used to seperate and disperse the nanotubes on a substrate so that they are nicely seperated and can be imaged by AFM?

Any help would be highly appreciated.

Thank you.
