Tailoring the biodegradability and bioactivity of green-electrospun polycaprolactone fibers by incorporation of bioactive glass nanoparticles for guided bone regeneration

•PCL membranes were produced with varying bioactive glass nanoparticles (BGn) amount.•BGn dispersion was achieved, leading to enhanced fibers’ uniformity, alignment, and wettability.•Biodegradation test demonstrated that the degradation rate was tailored as a function of BGn amount.•Bioactivity test showed that samples with 10 and 15 %wt of BGn exhibited induced HAp deposition.
