SILICON NITRIDE PROBES

AppNano offers two series of silicon nitride cantilevered probes:

  • Hydra series- a hybrid probe with nitride cantilever and a silicon tip and
  • Nitra series- features both the cantilever and tip made up of silicon nitride

HYDRA SERIES:

  • HYDRA probes are the world’s first true hybrid probes- low stress silicon nitride cantilevers integrated with sharp single crystal silicon tips
  • Silicon tip is integrated on a silicon pad for increased laser reflectivity without metal coating
  • This unique design ensures stable imaging in liquid without thermal drift
  • Available in rectangular (R) or triangular (V) shaped cantilevers of different lengths and thickness to enable various modes of AFM in both air/liquid media
  • Ideal for imaging soft biological samples in their aqueous environment
  • Silicon tips can be made hydrophobic or hydrophilic for functionalization studies
  • Tip can be made conductive by backside metal coating for electrical measurements
HYDRA-2R-50N: For Contact /Spectroscopy/ Tapping™ applications in liquid
HYDRA-2R-100N: Ideally suited for Contact mode in liquid
HYDRA-6R-100N: For Tapping mode in liquid/air
HYDRA-6R-200N: For Contact mode/Spectroscopy applications in liquid
