Veeco's Sharp Nitride Lever Probes Enable Superior Resolution in AFM Imaging

(Nanowerk News) Veeco Instruments Inc., a leading provider of scanning probe microscopes (SPM) to the nanoscience community, now manufactures new Sharp Nitride Lever (SNL) Probes that provide breakthrough atomic force microscope (AFM) imaging resolution and longer probe lifetimes, without higher expenses.

The AFM community has long desired a silicon nitride lever with a sharper tip for imaging in fluids. Veeco’s revolutionary hybrid SiN/Si manufacturing process has enabled the realization of this goal by combining the low spring constant softness of a silicon nitride cantilever with the sharpness of a silicon tip. This process has dramatically improved the traditional probe radii limits of 10 to 20 nanometers to a radius of curvature as low as 2 nanometers. These probes have already delivered unprecedented high-resolution imaging in both air and fluid with Contact Mode and TappingMode™ operation.
Other features worth mentioning:
  • The new SNL Probes can be used on any AFM instrument
  • Two configurations are available, NP/DNP levers and MLCT/MSCT levers
  • The silicon tips can be functionalized easily for molecular recognition and other advanced applications
  • The SNL Probes are available immediately at www.VeecoProbes.com. In addition to the new SNL Probes, Veeco manufactures and sells the world’s most complete line of probes and accessories for current and next-generation AFM applications, including tips customized for electrical and magnetic applications, nanoindentation, and nearly every other advanced AFM technique.
