Microscopic cracks turn flexible coatings into electrically activated bacteria killers
Nanowerk ·
The Brief
- Tiny cracks in gallium-carbon nanotube coatings create electrical hotspots.
- After a brief 9-volt pulse, the coatings kill over 80% of bacteria.
- The flexible coatings are proposed as a basis for smart wound dressings.
Why it matters
It shows that a flexible coating can be made to kill bacteria on demand with a low-voltage pulse rather than relying only on chemical agents, which may matter for future wound-care materials.
