During the past decade, scanning electrochemical microscopy (SECM) has significantly advanced, with a notable increase in publications shifting from proof-of-concept to real-world applications. This technique has become essential for studying heterogeneous and homogeneous reactions, high-resolution imaging of various substrates, including biological cells, and microfabrication. As SECM is now widely utilized by research groups globally, a new edition of this monograph is timely, offering comprehensive reviews of its various aspects. The updated chapters provide essential experimental and theoretical background for those in the field. Chapters 1 through 5 cover the principles of SECM measurements, instrumentation, preparation of SECM probes, imaging methodologies, and theoretical foundations. Subsequent chapters focus on specific applications and are designed to be self-contained. While some familiarity with electrochemistry and physical chemistry is beneficial, the discussions are accessible for beginning graduate students. The book highlights SECM's utility across a range of interdisciplinary research, with applications spanning from biological systems to sensors and probing reactions at liquid-liquid interfaces.
