Discrete Nanoparticles of Ruta Graveolens Induces the Bacterial and Fungal Biofilm Inhibition

摘要

Ruta graveolens silver nanoparticles (AgNPs) showed the color change within 30 min and characterized using UV-visible spectra, Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). UV-visible spectrum of R. graveolens AgNPs showed the sharp peak at the wavelength of 440-560 nm. XRD patterns confirmed that crystalline nature of R. graveolens AgNPs and FTIR results revealed that phytochemical reaction of these R. graveolens is responsible for the synthesis of AgNPs. TEM results showed the size of the R. graveolens AgNPs around 30-50 nm with spherical and triangular nature. Further, the antibacterial and antibiofilm activity of R. graveolens AgNPs showed the effective inhibitory activity against clinically important Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans. Our findings suggest that R. graveolens AgNPs can be exploited toward the development of potential antibacterial agents for various biomedical and environmental applications.
