"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.
"In addition to the other advice already given:
1) Reduce the physical size of your sample as small as possible. More mass = more thermal vibrations.
2) Reduce the temperature of your sample (and room) as much as feasible and comfortably…"
"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."
"You need to narrow your question down, considerably. What nanoparticles, of which dimensions? What type of lasers, specifically what output spectrum and what hertz?
I would go out on a limb here and venture that there is…"

Ian Allen is now a member of Nanopaprika.eu - The International NanoScience Community
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!
The invertion of 10G optical transceiver has greatly increase the networking speed, for the science behind the transceiver, please check website and learn about CWDM SFP transceiver, www.fiberoptictransceiver.net
The XFP (10 Gigabit Small Form Factor Pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber.please visit www.xfptransceiver.com for more info
