Abstract
Development of electrochemical sensors and its research extends over a wide range of applications including clinical analysis, food safety, environmental monitoring, and many more. Electrochemical sensing devices are more convenient for the analytical determination of various electroactive analytes due to its simple fabrication procedure and the reliability in the obtained results. The sensitivity of the electrochemical sensors can be improved by using various chemically modified electrodes instead of traditional unmodified electrodes. Mechanically alloyed materials are one of the fascinating materials used for the modification of electrodes in the development of electrochemical sensors. Metal alloys and their nano porous structures provide good conductivity and high surface area making it more convenient for the sensing applications. The chapter summarizes the analytical characteristics of the mechanically synthesized metal alloys modified electrochemical sensors giving a special emphasis to various dyes, neurotransmitters, biological molecules, drugs, etc. as the target analytes.
