ABSTRACT
Nano-biosensors have several immediate applications in generic research to monitor the inherent nanoscale components of living cells. Chapter 5 illustrates the nano-biosensor technology; it is envisioned for the detection of chemical and biological threats such as pollutants, microbial contamination, viruses, communicable and genetic diseases, and cancer. It includes some of the latest applications of nano-biosensors in “point of care” diagnostics field, highlighting the fundamental differences in material characteristics realized at nano-size dimensions to detect specific molecular interactions, primarily through the detection of molecular biomarkers, such as proteins and nucleic acids. Next, the chapter evaluates the DNA array technology, which might play an important role in enabling nanofabrication, rapid and sensitive drug screening. Next, the chapter evaluates the DNA array technology, which might play an important role in enabling nanofabrication, rapid and sensitive drug screening. The development of this type of technology corrects, to some extent, the limiting causes of combinatorial chemistry for drug discovery. It also allows the creation of revolutionary biological devices for the detection and management of diseases. Finally, the applications of nano-biosensors in the detection of different molecules from industrial emissions whose impact on the environment affect the prosperity of human health are explored.
