Home-built cantilever array sensor devices operated in static or dynamic mode are used in the field of qualitative label free diagnostics. The device uses optical detection readout using either vertical cavity surface emitting laser sources or a movable fibre optical laser beam. The cantilever arrays are functionalized depending on the field of application (e.g. genomics, proteomics, small molecules). The array format allows differential readout of the signals arising from molecular recognition events on the sensor interface.
Technical Specifications (static mode)
8 cantilever arrays, pitch 250 µm, laser readout at 780nm or 630nm, fully temperature controlled with automatic fluidics. Mechanical noise level ~ 1nm.
Technical Specifications (dynamic mode)
8 cantilever arrays, pitch 250 µm, laser readout at 780nm or 630nm, fully temperature controlled with automatic fluidics. The micro-organism growth detection device has a computer controlled humidity regulation. Dynamic signals in the range from a few kHz up to ~ 1MHz are able to be analyzed. Noise level ~ 500 pg in liquids and a few pg in humid environment.
