An inkjet-printed bioactive paper sensor that reports ATP through odour generation

Analyst. 2014 Oct 7;139(19):4775-8. doi: 10.1039/c4an01113a.

Abstract

We describe an inkjet printed paper-based sensor that reports ATP by the enzyme catalysed hydrolysis of S-methyl-L-cysteine generating an odour (methyl mercaptan) that is easily detectable by the human nose.
