Abstract

Objective
Biosecurity, medical diagnostics, and environmental monitoring are just a few of the many areas that rely on biosensors (BSs). They can identify a wide variety of chemical and biological contaminants, including infectious diseases, pollutants, hazardous materials, and particular biomolecules. Biosensors can detect trace amounts of substances and are easy to use, scalable, inexpensive, and precise. Because of their low cost, user-friendliness, and adaptability, biosensors have become increasingly popular in the medical industry.

Results
Biosensors have been greatly improved with the incorporation of nanotechnology (NT), especially with regard to detection speed, selectivity, and sensitivity. In NT-based biosensors, nanomaterials (NMs) such nano-wires, Quantum Dots (QDs), Carbon Nanotubes (CNTs), and nano-rods are commonly utilized. Because of their large surface area, NMs improve sensitivity and enable more precise detection of compounds at low concentrations. As a result of their exceptional electrical and thermal conductivity, great carrying capacity, extraordinary durability, and changeable color, they provide an important role in the creation of reliable and efficient biosensors.
Conclusions
This paper delves into the integration of biosensors that are enabled by nanotechnology, namely NT-enabled BSs. It examines the principles, designs, and materials utilized to make these sensors. There is an emphasis on the expanding role of NT-based biosensors in fields as diverse as healthcare and environmental monitoring. Developing next-generation diagnostic tools, environmental monitoring devices, and biosecurity instruments is made more feasible by combining nanotechnology with biosensors. Due to the special characteristics of nanomaterials, NT-based biosensors could completely change the way we detect substances. They would be able to detect a wide variety of substances much more quickly, accurately, and with a high level of sensitivity, which would be great for research and practical uses in many fields.
