Because of the unique electrocatalytic capabilities of nanoscale materials, nanomaterials are being employed for the creation of electrochemical DNA biosensors. They provide tremendous opportunities to interface biological detection events with electronic signal transduction and to develop a new generation of bioelectronic devices with new functionality. Specifically, for applications in biosensors of DNA that are becoming a new interdisciplinary boundary between biological detection and material science, nanomaterials such as noble metal nanoparticles (AU, Pt), carbon nanotubes (CNTs), magnetic nanoparticles, quantum dots and metal oxide nanoparticles have been actively investigated. This article deals with some of the important advancements in this sector in recent years, addressing the problems and obstacles in order to stimulate a greater interest in the development of nanomaterial biosensors and enhancing their applications in the diagnosis and assessment of illness and food safety.
