Acetylcholinesterase-catalyzed hydrolysis allows ultrasensitive detection of pathogens with the naked eye

Angew Chem Int Ed Engl. 2013 Dec 23;52(52):14065-9. doi: 10.1002/anie.201307952. Epub 2013 Oct 23.

Abstract

This paper describes a rapid diagnostic platform for pathogen detection based on the acetylcholinesterase-catalyzed hydrolysis reaction. Owing to the signal amplification strategies, the sensitivity of this assay is comparable to that of PCR. In addition, the readout of this assay is based on the color change of solutions, which can be easily observed by the naked eye alone.

Keywords: acetylcholinesterase; analytical methods; gold; hydrolysis; nanoparticles.
