Bacterial infections are a major problem in bone tissue regeneration, thus it is essential to incorporate antibacterial properties within the bone implant materials1. Silver compounds are frequently used as antibacterial agents to prevent bacterial infections and numerous studies have shown that silver ions can be incorporated within the biocompatible and osteoconductive biomaterial hydroxyapatite (HAp) structure, but, so far, no study has thoroughly evaluated silver ion release rates in long term2. Therefore, in this study long term silver release from porous and dense scaffolds up to one year was studied and, furthermore, silver containing scaffolds were functionalized with sodium alginate and chitosan to ensure additional local anaesthetic drug – lidocaine hydrochloride, delivery.
