Kelvin probe force microscopy (KPFM) has been widely used to map nanoscale surface potentials of materials in ambient and ultra-high vacuum environments. However, to study and ultimately understand charge-related processes, e.g., in biological systems or to further improve energy storage devices such as electrochemical batteries, nanoscale surface potential measurements in liquid environments are required. Here, we describe the various implementations of KPFM-based approaches for measuring surface potentials in liquid environments. We provide practical guidelines for surface potential measurements and describe what other information can be obtained. Finally, we discuss potential applications and limitations of existing approaches and present possible solutions for the successful implementation of liquid KPFM.
