• -FTIR analysis was performed on PLA (monolithic), HA/PLA, and HA+NE2/PLA nanofiber samples, along with pure HA powder. The obtained spectra (Figure 7) confirmed effective shell coating, as only the characteristic bands of PLA were detected in the core–shell nanofibers. All three nanofiber membranes (NF

For core–shell samples, contact angles of 126.9° ± 9.8° and 129.8° ± 1.3° were observed for the samples without NE (HA/PLA) and with NE (HA+NE2/PLA), respectively.

• Sciences, Phenikaa University, Hanoi 12116, Vietnam 10.3762/bjnano.15.7 Abstract Hydrophobic berberine powder (BBR) and hydrophilic BBR nanoparticles (BBR NPs) were loaded into an electrospun polylactic acid (PLA) nanofiber scaffold for modulating the release behavior of BBR in an aqueous medium. The BBR

• release from the BBR/PLA and BBR NPs/PLA nanofiber scaffolds was investigated in relation to their chemical characteristics, BBR dispersion into nanofibers, and wettability. The BBR release profiles strongly influenced the antibacterial efficiency of the scaffolds over time. When the BBR was loaded, the

• BBR/PLA nanofiber scaffold exhibited an extremely hydrophobic feature, causing a triphasic release profile in which only 9.8 wt % of the loaded BBR was released in the first 24 h. This resulted in a negligible inhibitory effect against methicillin-resistant Staphylococcus aureus bacteria. Meanwhile
