The broader application of liposomes in regenerative medicine is hampered by their short half-life and inefficient retention at the site application. These disadvantages could be significantly reduced combination with nanofibers. We produced 2 different nanofiber-liposome systems present study, that is, blended within nanofibers core/shell embedded liposomes. Herein, we demonstrate blend electrospinning does not conserve intact In contrast, coaxial enables incorporation into report polyvinyl...
Electrospinning has enabled creation of excellent materials for a great number applications. Previously, it was based on less productive capillary spinners. The present study is recent efforts to elevate electrospinning technology an industrial level by simultaneously provoking innumerable polymeric jets from sufficiently large liquid surface increase productivity. Particularly, deals with free conductive liquids and validates formulated hypothesis that explains self-organization...
The history of electrospinning is briefly introduced at the beginning article. fundaments process are then analysed physically to be translated into a successful technology. Self-organisation fluid in perceived as consequence various instabilities, based on electrohydrodynamics and, thus, highlighted key factor, theorising subject successfully elevate it highly productive technology manufacture nano-scale materials. main physical principle self-organisation appearance unstable tiny capillary...
This study describes the application of a new technological parameter in alternating-current (AC) electrospinning process for enhancing electrospinnability and productivity polycaprolactone (PCL) electrospun nanofibers (ENF). High-voltage AC is influenced via changes both waveform frequency; however, overall contribution to PCL remains unclear. hypothesizes that electrospinnability, morphology, diameter ENF are dependent on frequency high-voltage signal. Thus, paper demonstrates...
Composite nanofibrous yarns (CNY), featuring a submicron electrospun sheath coated on micro-scale core yarn have gained attention within the academic and industrial communities due to their unique structure. When braided, these CNYs hold great promise as next-generation surgical yarns. However, large-scale production of using conventional electrospinning techniques remains technologically challenging, maintaining integrity fibrous during braiding presents further difficulties. Here, we...
Abstract Aims Semaglutide, a glucagon‐like peptide‐1 (GLP‐1) receptor agonist, has shown promising effects in reducing cardiovascular events patients with obesity and heart failure (HF) preserved ejection fraction (HFpEF) irrespective of concomitant diabetes. However, the exact mechanisms underlying its cardioprotective actions remain unclear. Our study investigates direct semaglutide on human cardiomyocytes, focusing calcium (Ca) sodium (Na) handling potential to improve myocardial...
Nanofibrous materials are essential components for a wide range of applications, particularly in the fields medicine and material engineering. These include protective materials, sensors, cosmetics, hygiene, filtration energy storage. The most widely used researched technology these is electrospinning. This method producing fibers yields highly promising results thanks to its versatility simplicity. Electrospinning employed multiple forms, among which needle needleless direct current (DC)...

Abstract Nanotechnologies allow the production of yarns containing nanofibres for use in composites, membranes and biomedical materials. Composite with a conventional thread core mechanical strength nanofibrous envelope functionality, e.g. biological, catalytic, have many advantages. Until now, such has been technologically difficult. Here, we show an approach to composite yarn whereby plume nanofibers generated by high throughput AC needleless collectorless electrospinning is wound around...
Crystalline properties of semicrystalline polymers are very important parameters that can influence the application area. The internal structure, like mentioned crystalline properties, be influenced by production technology itself and changing parameters. present work is devoted to testing electrospun centrifugal spun fibrous nanofibrous materials compare them foils granules made from same raw polymer. test setup reveals structural differences caused technology. Effects average molecular...
Wet electrospinning is a useful method for 3-dimensional structure control of nanofibrous materials.This innovative technology uses liquid collector instead the metal one commonly used standard electrospinning.The article compares internal structural features polycaprolactone (PCL) materials prepared by both technologies.We analyze influence different water/ethanol compositions as on morphology resultant materials.Scanning electron micro-photographs have revealed bimodal in wet electrospun...
We describe a method of fabrication nanoporous flexible probes which work as artificial proboscises. The challenge making with fast absorption rates and good retention capacity was addressed theoretically experimentally. This shows that the probe should possess two levels pore hierarchy: nanopores are needed to enhance capillary action micrometer pores required speed up fluid transport. model controlled verified in experiments. also demonstrated proboscises can be remotely by electric or...
Additive manufacturing, also called 3D printing, is an effective method for preparing scaffolds with defined structure and porosity. The disadvantage of the technique excessive smoothness printed fibers, which does not support cell adhesion. In present study, a scaffold was combined electrospun classic or structured nanofibers to promote Structured were used improve infiltration cells into scaffold. Electrospun layers connected fibers by gluing, thus enabling fabrication unlimited thickness....
