Abstract

In the current research, rare earth metal Erbium Tri-Oxide nanoparticles (ETO-NPS) have been successfully synthesized in the form of crystalline powder using microwave irradiation technique and characterized, further the effect of antimicrobial and anticancer studies are carried out against Pathogenic microorganism and MDA-MB-231 cell line respectively. To reveal the crystalline structure and size of ETO-NPs, powdered X-ray diffraction (XRD) analysis has been carried out. To find out the bandgap energy and various functional groups, the UV-Vis spectroscopy (UV-Vis) and Fourier transform infrared spectroscopy (FTIR) spectra are used respectively. In scanning electron microscopy (SEM) and transmission electron microscopy (TEM) instruments, the interaction or scattering of electrons with the synthesized ETO-NPs provides the topography (crystalline shape) of the sample which is useful to obtain the size and shape of the ETO-NPs. The major elements (Er and O) present in the synthesized sample will be confirmed using EDX analysis. Using the disk diffusion technique, the effective zone inhibition area is calculated to find out the effective role (toxic activity) of ETO-NPs against Bacillus SP, E.Coli, Aspergillus, and Mucor. Further, the activity of ETO-NPs against breast cancer-producing MDA-MB-231 cell lines is studied.
