Perspectives of Novel Poly(D,L-lactide-co-glycolide)/hydroxyapatite core-shell nanoparticles as carriers of antibiotics

Abstract

Local drug delivery for the treatment of infectious bone tissue diseases is a high importance topic in the field of biomedicine for a last two decades. [1] In general, some of the main problems related to controlled drug delivery of antibiotics are: (i) high initial burst effect with toxic outcome and (ii) low concentration of released drug during extended period of time with possibility for development of resistant spaces.[2] There are some examples suggesting that core-shell particles applied as carriers of drug are able to provide high control over the process of drug release and to prevent burst effect.[3,4] Therefore, the main goal of our work is to design material which will be able to provide these characteristics.
