As industries demand more refined and application-specific analytical tools, selective chemical detection continues to be a key growth driver in the electronic nose market.

• In May 2024, a research team led by Dmitry Rinberg at New York University Langone Health introduced a bio-electronic nose. This technology harnesses the sensory precision of the mammalian olfactory system without relying on behavioral responses. The bio-electronic nose delivers highly sensitive and selective chemical detection by directly decoding olfactory signals from the brain. Leveraging machine learning algorithms, the team developed a robust chemical sensing platform using a grid electrode array implanted on the surface of the mouse olfactory bulb. This setup enables continuous monitoring of neural responses to a broad spectrum of odorants and mixtures across different concentrations.
