Electrochemistry, as a subdivision of chemistry, describes the kind of physical chemistry where one studies the reactions occurring chemically and expresses these as electrical processes, playing an important role in the diagnosis and therapeutic procedures of diseases in the health field, particularly modern medicine. This art of science stands equally important in diagnosis and treatment, while developing biosensors at a preliminary stage, with glucose biosensors developed first and, in later stages, have seen applications for widespread use in assessing biomarkers for cholesterol and cancer, and are still in use to date. Therefore, with the developments in nanotechnology in this century, the development and AI integration of electrochemistry-based biosensors have marginally placed and strongly act as a bright hope in diagnosis and treatment. Biosensors stand as big players regarding monitoring diseases in medicine while offering early diagnosis and therapeutic approaches, like controlled drug release, that need more precision and specificity. More than this, this process allows the construction of less heavy and highly portable personal health monitoring systems. The present work aims to analyze the development of electrochemistry in health, its current situation, and developments with promise for the future.
