Encased cantilevers improve performance for imaging and force spectroscopy in liquid.
Cantilevers typically suffer from high viscous damping and added mass due to the surrounding liquid. We build a hollow, transparent, and hydrophobic encasement around the probe that prevents liquid from entering. The cantilever stays dry when submersed in water except for a few microns of the probe’s sharp tip that protrudes from the encasement to interact with your delicate sample. Operating the instrument becomes straightforward with lower drift and the ability to autotune a single high-Q resonance peak, as if you were operating in air.
