Antibacterial activities of mechanochemically synthesized perovskite strontium titanate ferrite metal oxide

- Perovskite STFx was synthesized by mechanochemical high-energy ball milling.
- STF0.8 shows excellent bactericidal effect in both light and dark conditions.
- Bactericidal mechanism is investigated to account for its excellent performance.
- Surface charge, high pH, Sr2+ and nano-size appear to be the key contributors.
