Abstract The shapes of micro‐ and nano‐products have profound influences on their functional performances, which has not received sufficient attention during the past several decades. Electrohydrodynamic atomization (EHDA) techniques, mainly include electrospinning electrospraying, are facile in manipulate products' shapes. In this review, generated using EHDA for modifying drug release profiles reviewed. These linear nanofibers, round micro‐/nano‐particles, beads‐on‐a‐string hybrids. They can be further divided into different kinds sub‐shapes, explored providing desired pulsatile release, sustained biphasic delayed pH‐sensitive release. Additionally, resulted from organizations electrospun nanofibers discussed delivery, inner structures considered together developing novel delivery systems. future, related shape–performance relationships at nanoscale, besides size, structure structure–performance relationships, would play important roles promoting developments field.

Alginate is a natural polymer with good biocompatible properties and potential polymeric material for the sustainable development replacement of petroleum derivatives. However, non-spinnability pure alginate solutions has hindered expansion applications. With continuous electrospinning technology, synthetic polymers, such as PEO PVA, are used co-spinning agents to increase spinnability alginate. Moreover, coaxial, parallel Janus, tertiary other diverse novel electrospun fiber structures prepared by multi-fluid have found new breakthrough problem poor spinning polymers. Meanwhile, effectively achieve multiple release modes drugs. The powerful combination electrostatic widely in many biomedical fields, tissue engineering, regenerative bioscaffolds, drug delivery, research fever continues climb. This particularly true controlled delivery aspect review provides brief overview alginate, introduces advances spinning, highlights progress alginate-based nanofibers achieving various modes, pulsed release, sustained biphasic responsive targeted release.

Dressings with multiple functional performances (such as hemostasis, promoting regeneration, analgesia, and anti-inflammatory effects) are highly desired in orthopedic surgery. Herein, several new kinds of medicated nanofibers loaded active ingredients for providing functions were prepared using the modified coaxial electrospinning processes. With an electrospinnable solution composed polycaprolactone fenoprofen core working fluid, different types unspinnable fluids (including pure solvent, nanosuspension containing tranexamic acid hydroxyapatite, dilute polymeric comprising acid, polyvinylpyrrolidone) explored to implement processes creating multifunctional nanofibers. Their morphologies inner structures assessed through scanning transmission electron microscopes, which all showed a linear format without discerned beads or spindles diameter smaller than 1.0 μm, some them had incomplete core–shell nanostructures, represented by symbol @. Additionally, strange details about sheaths’ topographies observed, included cracks, adhesions, embedded nanoparticles. XRD FTIR verified that drugs presented amorphous state, resulted from fine compatibility among involved components. All samples demonstrated have hydrophilic property exhibited lower water contact angle 40° 300 ms. In vitro dissolution tests indicated was released sustained manner over 6 h typical Fickian diffusion mechanism. Hemostatic intentional distribution on shell sections able endow rapid hemostatic effect within 60 s.

Abstract A dressing patch made of radially oriented poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanofibers was successfully manufactured with a modified electrospinning strategy. The as-electrospun PHBV nanofiber exhibited uniform and bead-free nanofibrous morphology innovative arrangement, which demonstrated to possess obviously improved mechanical property, increased surface hydrophilicity enhanced biological properties compared the control traditionally randomly pattern. Interestingly, it found that pattern could induce cell migration from periphery center along in rapid manner. To further improve biofunction patch, berberine (Beri, an isoquinoline alkaloid) two different concentrations were encapsulated into during electrospinning, present sustained drug release behavior for nearly one month. Importantly, addition Beri impart excellent anti-inflammatory property by significantly inhibiting secretion pro-inflammatory factors M1 macrophages, also showed additive influence on promoting proliferation human dermal fibroblasts (HDFs), as well growth E. coli, S. aureus C. albicans, Beri-free patch. In animal studies, electrospun loading high content accelerate healing process diabetic mouse full-thickness skin wound shortened time (100% closure rate after 18 days’ treatment) quality (improved collagen deposition, re-epithelialization neovascularization hair follicles). all, this study reported therapeutic strategy integrating physical cues multiple effective treatment hard-to-heal wounds.

Combination therapy with oral administration of several active ingredients is a popular clinical treatment for cancer. However, the traditional method has poor convenience, less safety, and low efficiency patients.
