Dual-functional sulfonated PEEK implants via graphene oxide–mediated BMP-2 gene delivery: enhanced osteogenic and antibacterial performance in vitro [PDF]
IntroductionPolyetheretherketone (PEEK) is a promising orthopedic implant material due to its bone-mimetic mechanical properties; however, its bioinert surface and susceptibility to bacterial colonization limit its clinical efficacy.

Targeting biofilm and virulence in Pseudomonas aeruginosa: AidH@SPEEK as a novel quorum-sensing inhibitor [PDF]
Pseudomonas aeruginosa (PA), a gram-negative opportunistic pathogen, poses severe risks to immunocompromised patients. Conventional antibiotics often fail due to toxicity and resistance, primarily linked to biofilm formation controlled by quorum sensing (
