Abstract
Synthesized cerium oxide nanoparticles (S-CeO2 NPs) and 1%, 5% and 10% zirconium doped CeO2 (Zr-doped CeO2) NPs were fabricated using aqueous leaf extract of Pometia pinnata. The synthesized NPs were characterized using standard techniques which confirmed successful synthesis of NPs with particle size ranging from 12 to 23 nm and band gap energy of 2.54–2.66 eV. Photoantioxidant activities showed enhanced activities under visible light irradiation in comparison to the dark condition in the dose-dependent study. Biofilm inhibition studies showed ~ 73% biofilm inhibition of Staphylococcus aureus at 512 µg/mL for S-CeO2, whereas 10% Zr-doped CeO2 NPs showed biofilm inhibition of 52.7%. The bactericidal tests showed killing properties at 1024 µg/mL of S-CeO2 NPs and at 512 µg/mL of 1% Zr-doped CeO2. Reduced bactericidal activities were observed for 5% and 10% Zr-doped CeO2. These studies showed that the fabricated NPs have both good photoantioxidant and antibacterial properties.

The role of bacterial biofilms in chronic infections

TL;DR: Evidence is presented to support a view that the biofilm lifestyle dominates chronic bacterial infections, where bacterial aggregation is the default mode, and that subsequent biofilm development progresses by adaptation to nutritional and environmental conditions.
