ABSTRACT
This chapter discusses the potential use of NanoTech, nanoparticles in different important areas and scientific terminology definition to be considered. Biotechnology is the use of living organisms and systems to develop or produce products, or any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use. Many of airborne particles such as bioaerosols are of biological origins involving bacteria, fungi, and viruses, which are able to rising allergenic, toxigenic diseases, or infection. The bactericidal mechanism has been improved by coatings on the surfaces and attracted increasing the interest to protect the environment and human health. A portable microbial biosensor array system will be promising in reducing the cost, time, and personnel required for detecting the water toxicity while intensive farming and industrialization have led to the release of various toxic compounds in our environment, causing an important pollution of aquatic ecosystems.
