Abstract

This paper describes properties of microplates (MTPs) with integrated, fluorescence-based sensors for pH and oxygen, and their application for enzyme screening and monitoring of bacterial respiratory activity. Thin, hydrophilic sensing films consisting of an analyte-sensitive indicator and a reference fluorophore, are deposited on the bottom of the MTP. This allows for calibration-free ...
