Abstract The wettability and adhesion of biological surfaces often depend on their periodically arranged hybrid micro–nano array structures. Various fabrication processes are designed to mimic biomimetic surfaces. This review summarizes the types structures analyzes methods based top‐down bottom‐up construction, including templating, etching, self‐assembly, electrospinning/electrospraying. focuses shape reconfiguration surface under physical stimuli, as well changes in material properties during process. In addition, applications composite fields droplet transport, properties, sensors, soft robotics also discussed, current challenges prospects this field identified.

Abstract: Periodontitis is a major threat to oral health, prompting scientists continuously study new treatment techniques. The nanofibrous membrane prepared via electrospinning has large specific surface area and high porosity. On the one hand, electrospun nanofibers can improve absorption capacity of proteins promote expression genes. other they cell adhesion properties prevent fibroblasts from passing through barrier membrane. Therefore, unique advantages in periodontal treatment. At present, many membranes with antibacterial, anti-inflammatory, tissue regeneration have been for First, this paper introduces process. Then, commonly used polymers treating periodontitis are summarized. Finally, different types presented, future evolution treat described. Graphical Keywords: periodontitis, electrospinning, membrane,

Nanotechnology is one of the most promising technologies available today, holding tremendous potential for biomedical and healthcare applications. In this field, there an increasing interest in use polymeric micro/nanofibers construction structures. Due to its applications various fields like pharmaceutics biomedicine, electrospinning process has gained considerable attention producing nano-sized fibers. Electrospun nanofiber membranes have been used drug delivery, controlled release, regenerative medicine, tissue engineering, biosensing, stent coating, implants, cosmetics, facial masks, theranostics. Various natural synthetic polymers successfully electrospun into ultrafine Although biopolymers demonstrate exciting properties such as good biocompatibility, non-toxicity, biodegradability, they possess poor mechanical properties. Hybrid nanofibers from bio combine characteristics with those polymers, high strength stability. addition, a variety functional agents, nanoparticles biomolecules, can be incorporated create multifunctional hybrid nanofibers. remarkable nanofibers, latest research on unique highlighted study. Moreover, established fabrication techniques, especially electrospinning-based methods, well emerging strategies characterization are summarized. Finally, development application discussed.

The timely and effective control repair of wound bleeding is a key research issue all over the world. From traditional compression hemostasis to variety new hemostatic methods, people have more comprehensive understanding mechanism structure function different types dressings. Electrospun nanofibers stand out with nano size, high specific surface area, higher porosity, complex structures. They are high-quality materials that can effectively promote healing because they imitate structural characteristics skin extracellular matrix (ECM) support cell adhesion angiogenesis. At same time, combined amino acid polymers good biocompatibility not only has compatibility human body but also be drugs further improve effect dressing. This paper summarizes application electrospun dressings, analyzes in preparation application, looks forward development directions poly(amino acid) dressings hemostasis.

Side-by-side electrospinning is a powerful but challenging technology that can be used to prepare Janus nanofibers for various applications. In this work, cellulose acetate (CA) and polycaprolactone (PCL) were as polymer carriers silver nanoparticles (Ag NPs) lavender oil (LO), respectively, processing these into two-compartment fibers. A bespoke spinneret was facilitate the process prevent separation of working fluids. The side-by-side recorded with digital camera, morphology internal structure products characterized by electron microscopy. Clear fibers are seen. X-ray diffraction patterns demonstrate have been successfully loaded on CA side, infrared spectroscopy indicates LO dispersed PCL side. Wetting ability antibacterial properties suggested PCL-LO//CA-Ag NPs formulation had strong activity, performing better than containing only one active component. 20.08 ± 0.63 mm inhibition zone E. coli 19.75 0.96 S. aureus.

In a drug delivery system, the physicochemical properties of polymeric matrix have positive impact on bioavailability poorly water-soluble drugs. this work, monolithic F1 fibers and coaxial F2 were successfully prepared using polyvinylpyrrolidone as main polymer for loading curcumin (Cur) model drug. The hydrophobic poly (3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) was designed blank layer to change hydrophilicity fiber restrain dissolution rate. curved linear morphology without beads straight with few spindles characterized field-emission environmental scanning electron microscopy. amorphous forms its good compatibility verified by X-ray diffraction attenuated total reflectance Fourier transformed infrared spectroscopy. Surface wettability data showed that weaker (31.42° ± 3.07°) had 24 h Cur dissolution, which much longer than better hydrophilic (15.31° 2.79°) dissolved in 4 h.

One of the most important trends in developments electrospinning is to combine itself with traditional materials production and transformation methods take advantage unique properties nanofibers. In this research, single-fluid blending process was combined casting film method fabricate a medicated double-layer hybrid provide dual-phase drug controlled release profile, ibuprofen (IBU) as common model poorly water-soluble ethyl cellulose (EC) polyvinylpyrrolidone (PVP) K60 polymeric excipients. Electrospun IBU-PVP nanofibers (F7), IBU-EC films (F8) (DHFs, F9) one layer electrospun containing IBU PVP other IBU, EC PVP, were prepared successfully. The SEM assessments demonstrated that F7 linear morphologies without beads or spindles, F8 solid films, F9 composed porous fibrous layer. XRD FTIR results verified both compatible IBU. vitro dissolution tests indicated able pulsatile release, offered typical sustained whereas exhibit 40.3 ± 5.1% first phase for manner residues released an extended second phase. DHFs from combination pave new way developing novel functional materials.
