A minireview of copper material applications in bioelectrochemical sensing

Copper is an important metal in analytical and industrial fields as it has excellent thermal and electrical properties. In many disciplines, nano-Cu pays more attention than other noble metals nanoparticles. Attractive are its natural abundance, low costs and high activity toward many analytes. Extensive use has brought new types of sensors and practical implementations. The objective of this paper is to present crucial developments of copper material as a sensor. Practical applications in environmental, technological, and medical sensors were presented.
