Summary: The search for higher-quality nanomaterials for medicinal applications is ongoing. Electrospun fibers, which have similarities with natural tissues, have made significant progress in medical applications. Combining nanoparticles and nanofibers in composite materials allows for additional functions, such as photothermal, magnetic response, biosensing, antibacterial, drug delivery, and biosensing. There are two primary ways to prepare nanofiber and nanoparticle hybrids (NNHs): through single-step electrospinning or through the self-assembly technique. This paper focuses on the application of NNHs in drug release, antibacterial effects, and tissue engineering, utilizing biocompatible polymer composites.

Summary: Electrospun nanofiber membranes have great potential in various applications, but the understanding of their mechanical behavior and deformation is still limited. In this study, the mechanical behavior of polymeric nanofiber membranes with different fiber orientations (random and aligned) was extensively analyzed. The results showed variations in stiffness, ultimate strength, and ultimate strain between membranes with different fiber orientations, indicating the versatility and tunability of these nanofiber membranes' mechanical behavior. At the microscale, the fibrous structure of the membranes resists failure formation and progression, resulting in high fracture resistance.

Summary: In recent years, the use of polycaprolactone/silk (PCL/S) blend micro/nanofibers for biomaterial applications has been explored due to their beneficial combination of biodegradability, biocompatibility, and bioactivity. However, the conventional form of these fibers (mats) has limited use due to poor mechanical properties. To overcome this issue, nanofiber yarns (NF-Ys) have been fabricated, combining the advantages of nanofibers with superior mechanical properties. This paper investigates the production of PCL/S NF-Ys by electrospinning and explores the effect of composition and processing parameters on the morphology, tensile properties, and processability of these nanofibers.
