ph sensors advancesCongratulations to our Ph.D. students Federico Vivaldi, Noemi Poma and Andrea Bonini, from the Chemistry Lab for Analytical Technologies and Sensors (CATS), for their recent review entitled "Recent advances in optical, electrochemical and field effect pH sensors". Although its first definition dates back to more than a century ago, pH and its measurement are still studied for improving the performance of current sensors in everyday analysis.

The gold standard is the glass electrode, but its intrinsic fragility and need of frequent calibration are pushing the research field towards alternative sensitive devices and materials. In this review, the most recent optical, electrochemical, and transistor‐based sensors are described to provide an overview on the status of the scientific efforts towards pH sensing.
