Fluid manipulation inside the cantilever. (a) A chip containing 5 independent type-B cantilevers was used for the initial pipetting experiments. Aperture was made only on the middle cantilever. Applying positive pressure, water was filled in the middle hollow AFM cantilever, and subsequently a droplet was formed outside the tip aperture. The droplet on the cantilever was subsequently aspirated back. (b) Type-A chip is bigger, hence higher volume are uptaken. Liquid meniscus can be seen inside the hollow cantilever as it was getting filled.
