Inorganic Particles Incorporated into Electrospun Nanofibers: Bioactivity and Antibacterial Properties

NaturalNatural or synthetic polymerSynthetic polymernanofibersPolymer nanofiber present great propertiesProperties that allow their use as scaffoldsScaffold for tissue engineeringTissue engineering, such as biocompatibilityBiocompatibility, good mechanical resistanceMechanical resistance, high superficial areaSuperficial area, and porous structurePorous structure, allowing cell infiltrationCell infiltration, adhesionAdhesion, and proliferationProliferation. These propertiesProperties are achieved by the morphologyMorphology control—a result of the parameters set used during the electrospinningElectrospinning process—but, no matter what parameter is studied, the lack of bioactivityBioactivity intrinsic to polymersPolymer cannot be changed. Additionally, considering the scaffoldScaffold’s final applicationApplications, the capability to prevent bacterial proliferationBacterial proliferation should also be a concern. In this scenario, the incorporation of inorganic bioactive particlesInorganic bioactive particle into the nanofibersNanofiber’ porous structurePorous structure has been performed to optimize its biological propertiesBiological properties.
