Copper loaded ureteral stent reduces encrustation

Reducing biofilm formation and encrustation of ureteral stent is urgent in clinic. A copper modified surface on polyurethane is prepared by grafting dopamine, which could conjugate copper and form a film that resists microbombs adherent and crystals deposition. The results surface is tested, which reveals its significant enhanced antibacterial and anti-encrustation properties compared to PU
