Nanowire-based sensor enables rapid identification of toxic indoor mold
Researchers have developed an electronic nose that can reliably detect and identify mold, which causes various health problems for humans and animals as well as damage to homes and other buildings and structures. As revealed in a study published in Advanced Sensor Research, the E-Nose uses nanowires that detect gas concentrations by measuring changes in electrical resistance, which...
Nanowire-based sensor enables rapid identification of toxic indoor mold
Researchers have developed an electronic nose that can reliably detect and identify mold, which causes various health problems for humans and animals as well as damage to homes and other buildings and structures.
As shown by a study published inAdvanced sensor researchThe E-Nose uses nanowires that detect gas concentrations by measuring changes in electrical resistance caused by the interaction of gas molecules with a sensing material. Experiments found that the e-nose can detect and identify two types of mold commonly found indoors:Stachybotrys chartarumAndChaetomium globosumeach grown individually on different substrates.
“Our results prove that the e-nose can not only detect but also identify the different mold genera, thus representing an important step towards rapid, objective and cost-effective monitoring of indoor air quality" wrote the authors.
