“…Due to the excitation of plasma resonances or inter band transitions, some metallic nanoparticle dispersions exhibit the unique bands/peaks (Kuber and D'Souza 2006). A similar result was obtained by other researchers (Ahmad et al 2003;Kathiresan et al 2009). The results of the FTIR used to identify the possible bio molecules responsible for the stabilization of the (Asmathunisha et al 2010).…”

To identify the larvicidal activities of silver nanoparticles synthesised with Avicennia marina leaf extract against the larvae of Aedes aegypti and Anopheleus stephensi, in vitro larvicidal activities such as LC 50 and LC 90 were assessed. Further, characterisation such as UV and FTIR analysis were carried out for the synthesised silver nanoparticles. The LC 50 value of the synthesised silver nanoparticles was identified as 4.374 and 7.406 mg/L for An. stephensi and Ae. aegypti larvae respectively. Further, the LC 90 values are also identified as 4.928 and 9.865 mg/L for An. stephensi and Ae. aegypti species respectively. The synthesised silver nanoparticles have maximum absorption at 420 nm with the average size of 60-95 nm. The FTIR data showed prominent peaks in

“…Currently, nanoparticles are considered as active and safe drugs to boost the antibacterial activity of conventional antibiotics, through exploit these new antimicrobials effectively with important antibiotics in synergistic combination therapy against pathogenic microorganism [11]. The combination of nanoparticles with existing antibiotics seems to be very enthralling option by combining the two treatment modalities.…”

The synthesis of biogenic nanoparticles from non-chemical resources has increased the drive toward understanding infection biology. Accordingly, we aimed to address the symbiotic antibiofilm effect of biogenic copper and zinc oxide nanoparticles with antimicrobials against multidrug resistant (MDR) pathogens. The minimum inhibitory concentration (MIC) of copper nanoparticles (CuNPs) and zinc oxide nanoparticles (ZnONPs) at the range from 2 to 128 lg/ml was calculated against Grampositive and Gram-negative pathogenic bacteria using a broth dilution method. Both nanoparticles have prime antibacterial activity compared with standard antibiotics (excluding against P.aeruginosa MTCC 741). A qualitative assessment of biofilm formation and collegial effect was performed using a modified test tube and the microtiter plate-based method by measuring the optical density and time kill of nanoparticles. The results demonstrated efficient antibiofilm activity of CuNPs in its lowest concentration than ZnONPs and antibiotics itself. In addition, significant enhancing antibiofilm effect was also shown by CuNPs in the presence of third generation antibiotics against Gram-negative and Gram-positive bacteria. A scanning electron microscopy (SEM) analysis was used to investigate the effect of the nanoparticles on morphological changes of Staphylococcus aureus. Current data highlights, biogenic CuNPs and ZnONPs could be used as an adjuvant for antibiotics in the treatment of bacterial infections.

Abstract:The development of green experimental processes for the synthesis of nanoparticles is a need in the field of nanotechnology. The synthesis of silver nanoparticles was achieved using Bacillus cereus supernatant and 1 mM silver nitrate. 100 mM glucose was found to quicken the rate of reaction of silver nanoparticles synthesis. UV-visible spectrophotometric analysis was carried out to assess the synthesis of silver nanoparticles. The synthesized silver nanoparticles were further characterized by using Nanoparticle Tracking Analyzer (NTA), Transmission Electron Microscope and Energy Dispersive X-ray spectra. These silver nanoparticles showed enhanced quorum quenching activity against Staphylococcus aureus biofilm and prevention of biofilm formation which can be seen under inverted microscope (40 X). The synergistic effect of silver nanoparticles along with antibiotics in biofilm quenching was found to be effective. In the near future, silver nanoparticles could be used in the treatment of infections caused by highly antibiotic resistant biofilm.
