Nanowire E-Nose Detects and Identifies Indoor Mold in Controlled Tests

Lab experiments show the device recognized two common species by tracking gas-triggered resistance changes.

Overview

  • A peer-reviewed study by Yang et al. in Advanced Sensor Research details a nanowire-based electronic nose for indoor mold detection (DOI: 10.1002/adsr.202500124).
  • The sensor reads shifts in electrical resistance when gas molecules interact with its sensing material.
  • In controlled trials, the system distinguished Stachybotrys chartarum and Chaetomium globosum grown separately on different substrates.
  • The authors describe the results as a step toward faster, objective, and cost-effective indoor air-quality monitoring.
  • Reports note health and property risks from mold and stress that broader species testing and real-world validation are still required.
