In this study, we applied an electrospinning (ES) method, which is mainly employed in the textile industry, to the field of pharmaceuticals. We developed and modified an ES instrument and then utilized it to produce methacrylic acid copolymer S (MAC) nano-fibers to prepare tablets. By attaching a conductor rod made from stainless steel to the central part of the nano-fiber-collection plate of t...

• Wound dressing with Janus superhydrophilic/superhydrophobic feature is designed. Superhydrophilic PCL-Gelatin fibers act as a pump-like suction layer. Suprehydrophobic side shows excellent anti-adhesion effect. Rational design of new wound materials aims to accelerate healing. Traditional hydrophilic dressings, however, tend cause retention exudate retention, which increases the risk bacteria...

In this study, a hybrid system consisting of 3D printed polycaprolactone (PCL) filled with hydrogel was developed as an application for reconstruction of long bone defects, which are innately difficult to repair due to large missing segments of bone. A 3D printed gyroid scaffold of PCL allowed a larger amount of hydrogel to be loaded within the scaffolds as compared to 3D printed mesh and honey...

Abstract As efforts to replace nonsustainable plastics increase, biocomposites from cellulose fibers and biodegradable polymers like poly(ε‐caprolactone) (PCL) are promising candidates. The necessary adhesion between matrix can be achieved by grafting polymeric chains onto the fibers. Herein, we report of PCL Abaca (AFs), a one‐pot method obtain composite containing grafted fiber free PCL, char...

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

We elucidate the effects of incorporating surfactants into electrospun poly (ɛ-caprolactone) (PCL) scaffolds on network homogeneity, cellular adherence and osteogenic differentiation. Lecithin was added with a range of concentrations to PCL solutions, which were electrospun to yield functionalized scaffolds. Addition of lecithin yielded a dose-dependent reduction in scaffold hydrophobicity, whi...

Herein, hydroxypropyl-beta-cyclodextrin (HPβCD) inclusion complex (IC) of a hydrophobic drug, sulfisoxazole (SFS) was incorporated in hydroxypropyl cellulose (HPC) nanofibers (HPC/SFS/HPβCD-IC-NF) via electrospinning. SFS/HPβCD-IC was characterized by DSC to investigate the formation of inclusion complex and the stoichiometry of the complex was determined by Job's plot. Modeling studies were al...

BACKGROUND The interaction of stem cells with their culture substrates is critical in controlling their fate and function. Declining stemness of adult-derived human mesenchymal stem cells (hMSCs) during in vitro expansion on tissue culture polystyrene (TCPS) severely limits their therapeutic efficacy prior to cell transplantation into damaged tissues. Thus, various formats of natural and synthe...

Abstract A crucial property for the evaluation of bioinks, besides biocompatibility, is printability, which determined by resolution and shape fidelity. Recently, fiber reinforcement was used to overcome rheological limitations introduce biomimetic structuring. This study provides a systematic approach evaluate printability reinforced hydrogels. Alginate Pluronic hydrogels were blended with cel...
