Multi-sensor system for rapid detection of dangerous and hazardous agents

The project aims at developing of the next generation portable multi-sensor systems for continuous monitoring of environmental odors, quantitative detection of harmful emissions and contaminations. The highly ordered arrays of functionalized metal oxide nanowires will be prepared using bottom-up approach combined with innovative lift-off technique. Crucial technical and industrial challenges will be addressed during the project. The highly stable nanotechnology-based sensors will be integrated into an existing hardware multi-sensor platform featured by low power consumption. The project aims to validate the cost-effective handled-sensor system with long operation time for fast identification the cause of hazardous chemical agents and odor nuisance.

Project outline

The metal oxide nanowires will be deposited using bottom-up approach combined with innovative lift-off technique that introduces a clear technological breakthrough. The as prepared nanowires will be detached from the growth substrate and aligned between electrodes. The arrays of parallel aligned nanowires possess features and superiorities of singe nanowire, but facilitate the overall manipulation and guarantees higher reproducibility and industrial scalability of the products. Due to almost monocrystalline perfection and atomically sharp terminations, nanowires exhibit excellent chemical and thermal stability that make them superior to conventionally used polycrystalline thin-film sensors. Modelling activity: quantum chemical modelling helps to tune sensors against the specific hazardous agents by functionalization of the nanowires with specific end-functional groups and photoactive receptors.
