Efficient inactivation of influenza virus through adsorption of nanoceria and its oxidative power

Abstract

This study investigated the stabilizer's impact on nanoceria's antiviral activity. The positively charged nanoceria dispersion showed potent activity against the influenza virus, reducing the viral titer by over 4.0 log10 pfu/mL within 1 h, surpassing EN14476 criteria. It also inactivated the virus within 15 s, decreasing the infection titer by 2.2 log10 pfu/mL, and maintained efficacy even under bovine serum albumin loading.
