Fecha de publicación: | 28-nov-2005 | Editor: | American Institute of Physics | Citación: | Applied Physics Letters 87, 234102 (2005) | Resumen: | An optical readout technique has been developed for real-time monitoring of the profile of microcantilever arrays for sensing applications. The technique is based on the automated two-dimensional scanning of a laser beam by using voice-coil actuators. Cantilever profiles are obtained with subnanometer resolution and a processing speed of about ten cantilevers per second. The technique is applied for real-time monitoring of the adsorption of the alkylthiol mercaptohexanol in an aqueous environment by using an array of five microcantilevers. Molecular adsorption produces a cantilever strain that significantly differs from the Stoney's model. Main strain changes are strongly located near the cantilever clamping. | Versión del editor: | http://link.aip.org/link/?APPLAB/87/234102/1 http://dx.doi.org/10.1063/1.2136410 |
