New High-Speed Nano Imaging Device 67
Roland Piquepaille writes "Researchers at the Georgia Institute of Technology have built a new nano imaging device which is 100 times faster than current technology. Not only is the 'FIRAT' (Force sensing Integrated Readout and Active Tip) much faster than the current 'AFM' (atomic force microscopy), it also is able to take movies and to simultaneously capture several physical properties of nanostructures, such as stiffness, elasticity or viscosity. In fact, the FIRAT probe, which works like a microphone, could one day replace AFM. One of the researchers commented that 'We've multiplied each of the old capabilities by at least 10, and it has lots of new applications.'"

It's a slow process finding the resonance frequency, using the slow piezos to move the tip to the near field, and slowly scanning the area. One of the advantages of AFM is that it can be done on completely wet samples.
There's another technology called NSOM. [nist.gov] that does much the same thing. Many NSOMs are custom made. We use a Scanning Electron Microscope to check the tips we make to see if they are suitable. Tips are made by slowly stretching a glass wire inder high temperature until the break, giving you 2 NSOM tips.
Neat stuff.

This may be a great new technique, but there are so many problems with that little blurb, it's amazing. I'm sitting at an AFM right now doing a lot of what they say I shouldn't be able to. Incorporating the Z-actuator on the tip is nothing new, and people are already selling high speed AFMs, and have been for quite some time now.
The cool part is that current systems rely on a one dimensional oscillator to sense forces, while this relies on a two dimensional oscillator, and that seems to be better. The bad part is that it seems to require touching the surface (which is a big problem if you want to incorporate electric forces into your measurement).
