Nanobiosensors to detect environmental pollution

The presence of nanoparticles in nature is not recent since they naturally exist in great diversity from those produced by human activity to those of natural origin. This chapter discusses the use of nano-technology-based sensors for the detection of environmental pollution. The chapter focuses on the use of nano-biosensors, which combine nanotechnology with biological components, as promising tools for the detection and monitoring of environmental pollutants. The chapter highlights the dependence between nanoparticle synthesis and application design, as well as the importance of considering environmental considerations in the generation of nanoparticles. The use of nanotechnology is seen as a possible solution to problems that have influenced humanity for centuries, such as pollution, and the rise of the internet is intended to contribute to a model of analysis and follow-up of contaminant particles in an effective and reliable way.
