Abstract: A laser system for performing ophthalmologic procedures comprising a pulsed laser for emitting laser pulses, a focusing optics for generating at least one focal point in the anterior region of a patient's eye, a deflection device for varying the position of the focal point in the anterior region of the patient's eye, and a control unit for controlling the deflection device. The pulsed laser has a pulse duration in the range of nanoseconds, and the laser system is designed as a handheld device.

Abstract: A sensor chip for specific analysis of analytes in a liquid includes a plurality of sensor elements based on the SAW principle and applied as layer structures onto a surface of a substrate. A surface of each sensor element is coated with a sensitive substrate or coating having receptors specifically binding one analyte. During operation, the surface of the sensor chip rests against and seals a half-open covering part, with the covering part and the sensor chip forming a flow cell to be rinsed by the liquid. Conductor structures contact the sensor elements from the flow cell. More than six sensor elements are present which can each be triggered and read out separately via control and measuring electronics. At least two and in particular all sensor elements, are each coated with a differently sensitive substrate and the sensitive substrate is applied to the surface before attachment of the cover part.
