Projekt

The project goal is to build and test a nano microphone that utilizes a 1 nm thick carbon nanomembrane (CNM), made by polymerizing self-assembled monolayers, as a sensitive diaphragm that converts pressure changes into electrical signals. For this task the molecular CNMs and electronic circuits will be integrated into a functional nano electro-mechanical system (NEMS). The objective is to build a prototype that will be used for sound measurements in air, water, and in cell culture medium near and inside living cells. Furthermore, the intensity and frequency of sounds at different extra- and intracellular locations as well as in different physiological and developmental states of a living cell and during intercellular interactions will be investigated. The microphone will be tested for spatially and timely resolved extra- and intracellular sound measurements. Comparable to the patch-clamp technology, the data acquired by the nano microphone can provide answers to fundamental questions in biology.
