We developed a sensitive PPy/TiO2 based gas sensor coated on QCM substrate.
- class="label">•
We deposited the ultrathin film via simple layer-by-layer self-assembly approach.
- class="label">•
Its outperformance was strongly depended on the thickness of film.

The obtained gas sensor was sensitive to designed toxic gases at low concentration.

The gas sensor could be applied in evaluating shelf-life of typical foodstuffs.
