High Resolution TERS probes

Extremely dense, irregular and spiky coating of nanoparticles on a sharp silicon base tip to get a super-sharp resolution and a very high TERS signal.

high resolution probe TERS Next-tip nanoparticles coating

In High Resolution TERS probes, the spiky nanostructure formed at the apex is finished with one or two nanoparticles that provide great sharpness to the tip (up to 3 nm).

This sharp apex results in:

  • a very high spatial resolution
  • an increase of the lightning rod effect

Furthermore, this is achieved for different tip geometries
