DriveAFM

The Nanosurf DriveAFM is a top-of-the-line research AFM featuring photothermal cantilever excitation (BlueDrive technology), which eliminates acoustic forest artifacts and provides clean cantilever resonance curves in both air and liquid.

Key technology – BlueDrive photothermal excitation:
– Laser heats the cantilever directly at its base; avoids parasitic resonances from acoustic piezo excitation
– Clean resonance peak in liquid: critical for biological imaging where multiple spurious peaks complicate AM-AFM
– Direct drive: phase and amplitude response follow ideal simple harmonic oscillator; enables quantitative nanomechanics

Scanner and performance:
– XY scan range: 100×100 um (closed loop); Z range: 15 um
– XY noise: <30 pm RMS (closed loop); Z noise: <15 pm RMS - Scan speed: up to 4 lines/second for standard imaging; video-rate option available - Sample stage: 150 mm diameter; top-down optical access; temperature control option Operating modes: - Static force modes: contact, lateral force, force-distance - Dynamic modes: AM-AFM (tapping), FM-AFM, PFM (piezoresponse), MFM, EFM - Nanomechanics: PeakForce QNM (quantitative modulus, adhesion, deformation maps) - Liquid imaging: full immersion; closed fluid cell for biological samples - Conductance/KPFM: surface potential and work function mapping NewRoad provides Nanosurf DriveAFM in Israel with installation, training, and service support.
