Apparatus and method for detecting microorganisms

Abstract

The present invention relates to the fast detection of microorganisms, i.e. of bacteria, fungi, cells and other organisms, making use of methods and apparatuses coming from nanotechnology. According to the present invention, such organisms are detected using micromechanical sensor means known from many physical and chemical applications. One or more micromechanical cantilever sensors are either coated with a nutritive medium or at least partially built from a nutritive medium. By depositing a microorganism on the cantilever surface, preferably in a targeted way and in a controlled dosage, a “biological reaction” is started. This reaction results in a change of the mechanical and/or electrical properties of the sensor, i.e. the cantilever. These changes are determined, preferably at certain points in time, and thus allow the detection and detailed observation of the applied microorganism.
