Cefalexin-immobilized multi-walled carbon nanotubes show strong antimicrobial and anti-adhesion properties

▸ Cefalexin was immobilized on multi-walled carbon nanotubes (MWNTs) via poly (ethylene glycol). ▸ MWNT-cefalexin composites show strong antimicrobial activities. ▸ MWNT-cefalexin deposited film effectively inhibits cell adhesion.
