Aluminium nanoparticles (Al2O3NPs) have been synthesized in the presence of Ixora macrothysra flower extract at room temperature. The synthesized Al2O3NPs was characterized by UV-vis spectroscopy, SEM, EDS, XRD, SEM and FTIR. The UV-vis spectra of the Al2O3NPs show SPR band 278 nm for fresh sample and 270 nm for dried sample. SEM results indicate that Al2O3NPs are accumulated and cluster like in structure and the particle size of the Aluminium nanoparticles for fresh and dried sample synthesized were 20.73 nm and 27 nm respectively. Antibacterial activity of the synthesized Al2O3NPs has been assessed against P.aeruginosa and S. pyogenes. The results show that Al2O3NPs exhibit inhibitory effect and effect is a function of Al2O3NPs concentration. The antibacterial activity of the prepared Al2O3NPs has been compared with the extracts of the flower samples. It is found that the Al2O3 perform better than the flower extracts.
