It is conspicuous from various studies that the metal based nanoparticles is found to be an effective antimicrobial agent against several common pathogenic microorganisms.(Nanoparticles and potential apps, Biomedical applications,Antimicrobial activities of silver nanoparticles, Green synthesis, A review on plants extract mediated, Antimicrobial Properties).It is multidisciplinary area where in nanotechnology has led to major developments in health and medicine due to the integration the biotechnology in it (heralding new future-jyothi s a bhat). Nanoparticles such as silver, gold, zinc oxide and titanium oxide are being adopted as antimicrobials and additives in various aspects of consumers, health and industrial products(Nanoparticles and

Silver nanoparticles have been widely considered as a novel therapeutic agent to have a strong inhibitory and bactericidal effects.(biosynthesis of nanopartices by MOs) They interact with phosphorous moieties in DNA resulting in inactivation of DNA replication. Several forms of silver have been demonstrated to be effective against severe chronic osteomyelitis, burns urinary tract infections and even central venous catheter infections. Also silver exhibited excellent antibacterial effect when treated to implant materials coated with hydroxyapatite(A mechanistic study of antibacterial effect of silver ions).Microbial experiments has implied that interaction of Ag+ with thiol group played an essential role in bacterial inactivation. Silver Silver nanoparticles have inhibitory activity against Gram positive bacteria and Gram negative bacteria as well. Several experiments conducted against E.coli, B. subtilis, SS. aureus, methicillin-resistant coagulase-negative staphylococci, vancomycin-resistant Enterococcus faecium, ESBL-positive K pneumonia, S. typhi, V cholera to analyse the inhibitory effects of silver nanoparticles.The antibacterial activity are related to the total surface area of the nanoparticles. Larger surface area have a greater antibacterial activity.(nanoparticles and their potential,Silver colloid nanoparticles: synthesis, characterization, …show more content…
Several tests showed a slight improvement in the antibacterial activity of aluminium nanoparticles with antibiotics against few pathogenic strains of bacteria. However there are not much significant reviews on the antimicrobial properties of metal oxides nanoparticles with alumina in particular. Studies have indicated that alumina nanoparticles had a mild inhibitory effect against pathogenic strains of bacteria at higher concentrations. Alumina nanoparticles are also adopted for drug delivery systems due to their potential scavenging behaviour.(Nanoparticles: a boon to drug delivery, therapeutics, diagnostics and imaging. Parveen S1, Misra R, Sahoo SK.) The scavenging property has been related to act as direct antioxidants, block ROS production and also cause a reduction in ROS
