In Situ pH Modulation for Enhanced Chemical Sensing: Strategies and Applications
pH is one of the key parameters in chemistry and impacts almost all chemical and biological processes. Also, within analytical chemistry and sensing, pH plays a critical role. This review underscores the critical role of pH manipulation in overcoming analytical challenges posed by complex sample matrices and dynamic environmental conditions. It explores the available tools to control pH at a local scale and how those are or can be applied to improve sensor performance. We focus on four key areas where pH modulation has been or could be leveraged to advance chemical sensing capabilities: i) sensing alkalinity and buffer capacity, ii) sample pretreatment, iii) sensing pH dependent analytes and iv) reducing biofouling. We analyze existing strategies, but also try to identify unexplored possibilities which may have potential and can be exploited for sensing.
