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.
