Abstract: Fungi have emerged as an innovative method synthesis of nanoparticles. In the present study, we have reported the synthesis of Cerium oxide nanoparticles (CeO2 NPs) using Trichoderma viridae culture filtrate. The nanoparticles were characterized by UV–Visible spectrometry, Xray diffraction (XRD), Scanning electron Microscopy (SEM), Fourier transform Infrared Spectrometry (FT-IR) and dynamic light scattering (DLS) analyses. UV–Vis spectral analysis reveals the formation of CeO2 NPs and the functional groups present in the fungal filtrate responsible for the synthesis of NPs were analysed by FT-IR. The XRD, SEM and DLS analysis confirmed the cubic structure of CeO2 NPs and spherical shape, with the particle size of around 68nm. The high negative zeta potential value and its free radical scavenging activity indicate the stability and potent antioxidant property of the synthesized nanoparticles. The synthesis of CeO2 NPs utilising fungi is a simple, cost-effective and green approach and further studies have to carry out to understand its efficacy in preventing oxidative stress related diseases.
