MULTISENSE – A new approach for multiple gas sensing with high sensitivity and selectivity

Project goal: MULTISENSE aims to develop a new gas analyzer whose working principle is based on splitting rotational levels of the gas molecules in a DC electric field and reaching resonance in an AC electric or magnetic field.

About the project:  The major outcomes of the MULTISENSE are experimental confirmation of the new detection mechanism and the developed lab prototype of the gas analyzer for sensitive and selective detection of gases. The proposed mechanism favors a physisorption as the main interaction of gas sensing materials with gas molecules allowing the detection of a specific gas from a gas mixture with a high selectivity and sensitivity at room temperature. Due to their physicochemical properties and microstructure, 2D materials and metal-oxide semiconductors are chosen as materials of interest for developing new gas sensors. The project will have a long-term impact on the gas sensor market, medical devices for breath analysis, healthcare, and society in general.

BioSense role on the project: BioSense Institute contributes to the project through its expertise in material characterization and the use of advanced research infrastructure. BioSense researchers lead one work package, ensuring the coordination and implementation of experimental activities. Within the project, they utilize specialized instruments and methodologies available in our laboratories (BET analysis, Zetasizer, and other techniques for nanomaterial characterization), enabling precise validation of new sensor concepts. In this way, BioSense provides critical support in the development of a laboratory prototype of a gas analyzer, combining its infrastructure and expertise with an innovative research approach. Through this contribution, BioSense positions itself as an important partner in the implementation of new gas detection technologies, with potential impact on the sensor market, medical diagnostics, and society as a whole.
