We present a novel chemical sensor based on a microfabricated array of silicon cantilevers. Individual cantilevers are sensitized for the detection of analytes using metal coatings. Analyte molecules chemisorbing or physisorbing on the cantilever coating and chemical reactions produce a change in interfacial stress between analyte molecules and cantilever.(More)
A cantilever-based protein biosensor has been developed providing a customizable multilayer platform for the detection of antibodies. It consists of a biotin-terminated PEG layer pre-functionalized on the gold-coated cantilever surface, onto which NeutrAvidin is adsorbed through biotin/NeutrAvidin specific binding. NeutrAvidin is used as a bridge layer(More)
Nanomechanical cantilevers are small and thin, microfabricated silicon beams. They serve as extremely sensitive mechanical sensors, which transform processes occurring at their surface into a mechanical response. This unique signal transduction principle allows to measure surface stress occurring at the cantilever surface by monitoring the bending of the(More)
