Abstract

Abstract Candida albicans produces various quorum sensing molecules (QSMs) which are involved in biological processes, e.g. morphological changes or biofilm formation. Thus, a sensitive and selective electrochemical assay was developed for determination of tryptophol as one of the most important QSMs. Preparation, characterization, and testing the electrocatalytic activity of prepared sensors with various sensing elements and nanomaterials were investigated. In addition, the effects of supporting electrolytes, pH of buffer solutions, scan rate, and possible interferences on the response of tryptophol
