Abstract

The cover image illustrates the principle of a newly developed chemiluminescence (CL) microfluidic paper-based analytical device (μPAD) that enables highly sensitive detection of any catalytic process in which H2O2 is produced. Through the use of a new, sensitive CL luminophore cell phone camera detection allows quantification on-site with the same sensitivity as afforded through a CCD camera in the lab. One-step reactions to time the catalytic reactions can easily be realized through a moveable barrier if desired. Lactate is detected with μM detection limits and three orders of magnitude dynamic range in sweat, the luminophore reaches a pM detection limit. Cover design by Simone Rink. More information can be found in the Research Article by Antje Baeumner and co-workers .
