Study of th e Biocidal Effects of Nanotube Single W all, Nano tube Multi Wall, Fe and Al۲O۳ Nanoparticles by B iosensor

There are many risks associated with Nanoscale particles. Because of small si ze of Nano materials and a high surface to volume ratio, t hey tend to be more r eactive. The high reacti vity leads t o an increas e in produ ction of active oxygen species (R OS) such a s free radicals. These free radicals attack other molecules, particularly lipids, proteins, and n ucleic acids causing an increase in cell mem brane fatty acid peroxidation, ev entually causing damag e, inflamm ation, and cell death.Our Biosensor is composed of two parts: a biological section ma de of a luminescence bacteria called vibrio fischeri and an electrical device calle d luminometer which help to ex amine bacterial exposure in a variety of conditions [۱,۲].
