Nanocomposite antimicrobials prevent bacterial growth through the enzyme-like activity of Bi-doped cerium dioxide (Ce1−xBixO2−δ)

Ce_1−xBi_xO_2−δis an active halogenation catalyst with maximum activity forx≈ 0.2 due to the effects of zeta-potential and BET surface area. Ce_1−xBi_xO_2−δ/polyethersulfone nanocomposites block bacterial biofilm formation of Gram-negative bacteria.
