Abstract

Staphylococcus aureus is a leading cause of healthcare-associated infections, particularly through biofilm formation on medical devices, leading to severe and recurrent complications¹. The resistance of S. aureus biofilms to traditional antibiotics requires new strategies to mitigate these infections. Our previous findings indicate that the anti-biofilm properties of carbon-infiltrated carbon nanotubes (CICNT) significantly inhibit the growth of S. aureus biofilms². We will further explore if copper, an innately antimicrobial material, will enhance this effect.

To determine the impact that copper would have on bacterial growth, we coated the CICNT with a thin layer of copper and used colony-forming unit analysis to determine the difference. Our prediction was that the structure of CICNT combined with the copper coating would inhibit the formation of S. aureus biofilms.
