Expanding the line of TERS products


It's already 7 years have passed since we manufactured our first TERS-active cantilevers, - and their characteristics and results constantly grow up and improve all this time. Just recently NT-MDT SI engineers have showed TERS in liquid on an opaque sample, using our cantilevers.

And now we're glad to present the new product - TERS demonstration, - which would be interesting so for new AFM-Raman researchers as for experienced specialists.

To detect Tip-Enhanced Raman Scattering is a tricky task, which becomes a deal of the independent research for every new type of sample. Before to start such a difficult investigation with the sample targeted it could be reasonable to polish metodology of the experiment with something more simple and reliable. As a starting point the one could took a combination of our TERS-activated cantilevers and specially prepared TERS_S sample. Using this couple experienced engineers from NT-MDT SI get Raman signal enhancement with almost 100% probability.

What could be better to start working with TERS? Only to speak with an experienced AFM-Raman engineer and to see how he gets Raman signal enhancement directly in your lab!

TERS_D demonstration service includes both 1 day of experienced AFM-Raman engineer's visit and 3 (or more) TERS-activated AFM probes which will stay at the customer's side after demonstration.
Using our TERS-activated cantilevers and TERS_S sample the engineer will demonstrate Raman signal enhancement in your laboratory. He will explain all his actions and make some important advices that should be remembered for further TERS experiments. Before and during the visit he will also examine configuration of your equipment and recommend some changes (if needed) to maximise Raman response in TERS mode. And of course he will be glad to answer on your questions about Raman measurements and TERS metodology.

Here at ScanSens GmbH we allways think about how to make recent acheivements in nanoscience more clear and available to everyone. We hope that the new service of TERS demonstration will help our customers to get excellent results in AFM and Raman using other our products, TERS cantilevers and test sample. If any questions appear, please, don't hesitate to contact our sales manager, Evgeniy Lisov (

You're always welcome!


New HOPG test samples available


Besides our wide assortment of AFM cantilevers and silicon grating some other products are also very popular between researchers from various countries. Highly oriented pyrolytic graphite is one of such products. This line of products was started many years ago in the restricted set of thickness and dimensions. From the very beginning we suggested that AFM scientists work with similar sample's holder and our assortment will be just enough to satisfy their needs. 

But now we meet very often requests from people, who are not assosiated with scanning probe microscopy at all. HOPG samples application field is very wide due to their structural flexibility and atomic smoothness.

So now, to meet all possible requirements, we decided to broaden our assortment of HOPG samples. We have added several samples of higher lateral size and thickness in all categories from A to H. As usually, you may check the whole assortment at the HOPG and test substrates' part of our web-site.

Single crystal diamond AFM probes with high aspect ratio



We’re glad to present the new product in our assortment: AFM cantilevers with single crystal diamond (SCD) tips. This type of probes is represented by a very narrow diamond (CVD-grown) needle glued to a standard tipless polysilicon cantilever.

AFM probes prepared by such technology show several features, especially relevant to AFM scans:

  • SCD tip’s cone angle is less than 10 degrees. Thus a diamond needle will get into deep trenches and between high particles, providing detailed topography images.
  • Single crystal diamond tip’s end is very hard. As the result wear of such cantilevers is several times slower than for standard silicon ones. Low deformation of a tip will be a great utility for elasticity investigations and simple nanoindentation or force lithography experiments.
  • SCD tip has got low surface energy and it works well for sticky biological samples.

SCD AFM cantilevers are constantly used by famous NT-MDT application scientists: Sergey Magonov and Marko Surtchev. Thus we’re absolutely sure in quality of these probes.

On the right image the one can see a scan of so-called “Black silicon” relief. Such surface can be constructed by a special etching experiment and is used in solar cells.

Main challenges in visualization of “black silicon” pyramids are their heights that reach 6-7 um. Standard cantilever can’t get between such high and densely grown structures. But as the one may see from the scan, SCD probes worked well. Sharp pyramid’s shape and well-defined flat areas between them approve high quality of the scan.

Now SCD cantilevers are presented in our assortment by the models HA_NC/SCD and HA_C/SCD with the same lever’s parameters as for corresponding ones of ETALON series. But by the request SCD needles can be glued to any types of tipless cantilevers of Golden and Etalon series.
