Abstract

We report simple and low-cost setup based on a modified DVD optical pickup unit for detection and photothermal actuation of microcantilever oscillations. Small rectangular cantilevers (length 7 μm, width 3 μm and thickness 100 nm) were successfully actuated and detected in both air and liquid environments. Applications of such a setup for microcantilever-based biochemical and physical sensors and in atomic force microscopy are envisaged.
