Chemiresistors vapor sensors composed of single-walled carbon nanotubes inkjet printed on paper and cloth (cellulosic substrates) can reversibly detect aggressive oxidizing vapors like nitrogen dioxide or chlorine at sub-ppm levels  in ambient air at room temperature without the aid of a vapor concentrator. Lightweight and highly flexible, these all-organic sensors can be bent to a crease without any significant loss of sensor function.
