Overview
- Researchers stacked one metal‑organic framework atop another to create sharp, precisely spaced nanotips that rupture bacteria on contact.
- Antibacterial performance depends on tip spacing, with gaps that are too wide allowing attachment and gaps that are too tight reducing lethal stress.
- The method avoids antibiotics and toxic metal‑ion release, aiming to curb resistance development and lessen environmental impact.
- Published in Advanced Science, the work points to potential use on implants, catheters, ship hulls and industrial pipes to deter biofouling.
- The team reports low‑temperature fabrication compatible with temperature‑sensitive and recycled plastics, with durability and biocompatibility testing still ahead.
