Nanoparticles are the simplest form of structures with particles between 1 and 100 nanometers. In principle any collection of atoms bonded together with a structural radius of < 100 nm can be considered a nanoparticle and are further classified accordingly. In nanotechnology, a particle is defined as a small object that behaves as a whole unit with respect to its transport and properties. Nanotechnology is helping to considerably improve, even revolutionize many technology and industry sectors and show rapidly growing benefits and applications in the fields of everyday materials process, electronics and IT applications, sustainable energy applications, environmental remedy applications, medical and healthcare applications, transportations etc.
With regard to Environmental remediation, there are many eco-friendly applications for nanotechnology, such as materials that provide clean water from polluted water sources in both large-scale and portable applications, to clean industrial water pollutants in ground water through chemical reactions, nanofabric paper towel, that can absorb 20 times its weight in oil for cleanup applications, mechanical filtration in vehicles, and ones that detect and clean up environmental contaminants. Now, researchers are involved to develop carbon nanotube “scrubbers,” and membranes to separate carbon dioxide from power plant exhaust.
This issue includes a research article that evaluates the impact of nanoparticles to remove the highly toxic textile dye using biological component, the microorganisms, from polluted water in a cost effective manner. Other interesting information like bacterial mechanism on soil networking, bacterial raincoat for crop production, the impact of soil fertility are also included.
