Abstract

A method for detecting a species indicative of microbial growth comprises: contacting a sample of interest with an oxidising agent to generate an oxidised species, subjecting the oxidised species to a varying applied voltage whilst measuring the current response, and analysing said current response to determine whether the oxidised species is indicative of microbial growth. Preferably, the sample contains one or more microbial volatile organic compounds (MVOCs), such as one or more C1-12 alcohol, aldehyde, ketone or ester compounds, and preferably one or more of 1-octen-3-ol, 3-octanone, and 3-octanol. The oxidising agent may be sodium hypochlorite. The method may use cyclic voltammetry, and the voltage may be varied over the range -2 V to +2 V. A handheld device suitable for putting the method into effect is also described. A method for detecting a species derived from a carbonyl compound is also disclosed.
