Tips for Cantilever

  • https://www.nanoandmore.com/
    • AC Mode (AIR):
      •  BudgetSensors Tap300: -G (uncoated), Al-G (aluminium coated), GD-G or GB-G (gold coated)
        • they are quite good standard tips (tip radius <10nm). Choose gold coated for liquid-AFM.
        • 10 pcs / ~200 €
      • Nanosensors PPP-NCx (Point Probe Plus - Non-Contact), NCH (higher frequency), NCL (lower frequency), NCR (aluminium coated), NCAuD (gold coated)
        • Slightly better in performance, but also more expensive.
        • 10 pcs / ~330 €
    • AC Mode (LIQUID):
      • BudgetSensors Multi75GD-G or Multi75GB-G (both gold coated)
        • Recommended for basic liquid-AFM using AC mode.
        • 10 pcs / ~260 €
    • Contact Mode:
      • AIR: BudgetSensors Contact-G (uncoated) or ContAl-G (aluminium coated) 10 pcs / ~200 €
      • LIQUID: BudgetSensors ContGD-G (gold coated) 10 pcs / ~260 €
      • Conductive-AFM:
        • PPP-ContPt (Nanosensors) orContPt (NanoWorld) 10 pcs / ~420-460 €
        • ElektriCont-G (BudgetSensors) 10 pcs / ~240 €

Calibration of AFM cantilever

The following link are useful in order to calibrate the spring constant of a cantilever. The

first method is the one I am more partial. The second was considered the gold standard

but the above method has gained respect.
