A model for controlled dosing of femto-litre volume liquids using hollow microcantilever

A hollow microcantilever is used instead of a conventional microcantilever to dispense and aspirate liquids in the femto-litre (10^-15 L) volume range in an atomic force microscope (AFM) setup. The inherent force sensing capability of the cantilever is used to monitor the fluid manipulation in-situ. At this small scale, parameters...
