Abstract:
Nano-biosensors have wide applications in several fields as they impart sensitivity, effectiveness, portability, compatibility, stability, viability, flexibility, and reliability. Indeed, the emergence of new techniques in biotechnology, custom-made bio-elements, and their biocompatibility, and nanotechnology played a fundamental role in the designing of nanocomposite biosensors. Therefore, nano-bio sensors have tremendous opportunities in biomedicine, healthcare (lab-o-chip diagnosis, patient’s drug compliance), personalized medicine, biotechnology, drug delivery, food processing industry, microbiology, agriculture, and defense services also. Now, traditional medical practices can be explored and advanced more with nano-biosensors by facilitating early ultrasensitive diagnosis, extended monitoring of disease biomarkers, diagnosis, treatment, in point-of-care devices and at-home healthcare instrumentation, and in timely therapy decisions. While compiling this chapter, the focus was placed on highlighted up-to-date research and commercialization of nano-biosensors in the biomedical area.
