NanoAndMore presents NANOSENSORS new highly conductive and wear resistant Platinum Silicide AFM Probes




Platinum silicide probes: highly conductive AFM probes with small radii and high wear resistance

Conductive diamond

Conductive Diamond

Conductive diamond probes. Advantages: hard, long-lasting coating. Disadvantages: large radius, low conductivity

The best of both worlds

Platinum silicide probes

Platinum silicide probes

Advantages: small radius, excellent conductivity, good wear-out behavior

Platinum coated probes

Platinum coated probes

Platinum(Iridium) coated probes. Advantages: relatively small radius, excellent conductivity. Disadvantages: fast wear-out

Extremely durable: C-AFM comparison of PtSi and Pt probes

Platinum silicide probes

Cross sections of current images of (a) a commercial Pt probe (Pt, left image) and (b) a PtSi probe (PtSi, right image).
TUNA mode, DI Icon, sample bias -0.25V, force 1μN, total tip travel distance 13mm. For each tip a cross section out of the first
and the last scan is shown.

Silicide tip advantages

  • Formation of a hard and massive conductive tip apex instead of only a few ten nanometer deposited metal coating at the tip apex
  • Smaller radius than PtIr coated probes. About 5 to 6 times smaller than diamond coated tips
  • Metal (PtIr) like conductivity. About 10 times better conductivity than conductive diamond
  • Dramatically reduced wear rates compared to silicon and PtIr coated tips

Welcome - about us

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
