RESEARCHERS AT PURDUE University have developed a treatment to infuse a hardened metal surface with naturally occurring antimicrobial peptides. The Purdue team’s technology creates a hard metal surface that kills bacteria that try to attach to the surface.
“When we create an oxidised metal surface with nanometre-wide and micrometre-deep cracks, peptides can be infused in these microscopic cracks with a simple wet process,” said David Bahr, head and professor of materials engineering at Purdue, who leads the team.
