Sustained antibiotic release is important to prevent the infections after surgical treatments such as guided tissue regeneration (GTR). Electrospinning provides a simple way to fabricate nanofibers for drug delivery. In this study, a simple method to achieve sustained antibiotic release by introducing mesoporous silica nanoparticles (MSNs)with electrospinning is developed. The nanoparticles entrapped nanofibers (MSNs-PCL) were successfully fabricated, and a sustained release of Gentamicin (cas 1403-66-3) was demonstrated. The gentamicin loaded MSNs-PCL showed strong antimicrobial effects against E. coli, indicated the sustained release behavior and the retained bioactivity. The MSNs-PCL synthesized by electrospinning method shows great potential for biomedical applications such as fabricating GTR membranes.
