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/PLAnanofiber 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/PLAnanofiber 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

Polymeric nanofibers have been widely used in many fields such as
4% to 12%) in the PLAnanofiber led to an increase in the nanofiber diameter and resulted in a higher burst effect and faster drug release. F2 coded nanofiber was chosen as the ideal PLAnanofiber with ideal drug concentration (8%) due to its favorable encapsulation efficiency, nanofiber diameter
