“…Nanosensors offer multiple abilities, including practicable operation, exceptional performance, high specificity and sensitivity, rapid response, condensed size, portability, and real-time analysis [45]. In these days, investigators improve the specificity and sensitivity of the methods by focusing on the nanosensor production quality, extending the affinity between the surface chemistries and employing nanocomposites, such as nanofilm [46], gold nanoparticle [47], or quantum dot [48], for signal amplification studies.…”
