SENSE 100 - Silicon nitride AFM probe
SENSE 100 - Silicon nitride AFM probe
Benefit from high quality imaging with our pack of 10 general purpose silicon nitride AFM probes, suitable for imaging soft samples using contact or AC mode in either air or liquid. They feature a sharp silicon tip integrated onto a silicon nitride cantilever with a gold reflective backside coating.
Spring constant: 0.1 N/m
Resonant frequency: 100 kHz

High quality imaging every time…
“We used the Sense 100 probes to image porous amphiphilic block-copolymer morphologies with a Cypher ES in intermittent-contact mode in air and in water. We were impressed by the good quality of the images, in particular the great contrast of the phase images. The Sense 100 probes proved their capability to image soft samples and could reveal the details of porous structures with high precision!” - Dr. Bizan N. Balzer, University of Freiburg, Germany
“The Sense 100 probes fill a very important niche for biological AFM - soft, and relatively small cantilevers that allow gentle imaging and low-noise force data at reasonable scan rates, but are still large enough to be used with conventional AFMs. They also have a tip that is tall enough to work with topographic samples (e.g. live bacteria) and sharp enough to image biomolecules.” - Dr Nic Mullin, University of Sheffield, UK
