Welcome

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!

Dr. András Paszternák, founder of Nanopaprika

Question about raman

Hello, all! As I know maximum resolution we can receive using RAMAN spectroscopy is 200 nm. NT-MDT claimed that they can get 14 nm. What do you think - is it possible at all?

What scope was it?

Wow. 14 nm is impressive.

They must be taking advantage of various sub-diffraction "cheats", similar to what is used with confocal microscopy to break the optical resolution limit, for example.  OP, you should post the article that makes the claim, at least.

Here is a recent article that uses AFM in conjunction with Raman Spectroscopy, they claim resolution all the way down to 2-10 nm by adjusting the angle of incidence of the excitation field.
