Chitosan (CS) nanofibers were electrospun from aqueous chitosan solution using concentrated acetic acid as a solvent. Polyethylene oxide (PEO) with varying weight content 10- 60 wt% was mixed that acted plasticizer to improve spinability of the prepared solution. With increase in PEO 10-50 viscosity resultant CS/PEO decreased 0.938 Pa-s 0.272 Pa-s, whereas higher concentration lower surface tension It found beadless nanofibrous mat obtained not less than 85% concentration, 50 and at 0.2 NaCl...
Tissue biofabrication that replicates an organ-specific architecture and function requires physiologically-relevant cell densities. Bioprinting using spheroids has the potential to create constructs with native densities, but its application is limited due lack of practical, scalable techniques. This study presents HITS-Bio (High-throughput Integrated Fabrication System for Bioprinting), a novel multiarray spheroid bioprinting technology enabling tissue fabrication by rapidly positioning...
Abstract This study was aimed at fabricating monetite nanoparticles impregnated gelatin-based composite scaffold to improve the chemical, mechanical and osteogenic properties. Scaffolds were fabricated using a freeze-drying technique of slurry containing varying proportion gelatin monetite. The lyophilized scaffolds cross-linked with 0.25 wt% glutaraldehyde solution obtain three-dimensional (3D) interconnected porous microstructure improved strength stability in physiological environment....
The present study focuses on the synthesis and characterization of hydroxyapatite-collagen nanoparticles incorporated polyanhydride paste investigating its bone regeneration capacity in vitro. Photocrosslinkable was prepared after synthesizing methacrylate derivatives 1,6-bis(p-carboxyphenoxy)hexane (MCPH) sebacic acid dimethacrylate (MSA). These multifunctional monomers, namely 45 wt% MSA, MCPH addition to 10 poly(ethylene glycol)diacrylate (PEGDA) were photopolymerized under ultraviolet...
Abstract In the current work, monetite (DCPA) nanoparticles incorporated chitosan (CH)‐based composite was prepared using by electrospinning technique. A smooth and defect‐free fibrous matrix with an average fiber diameter in range between 311 ± 13 to 380 28 nm obtained for 5 wt% (CH‐DCPA ) 7 DCPA containing electrospun scaffolds. The results indicated that addition of caused increase tensile strength scaffolds from 6.2 12.34 MPa. slow degradation rate (~37% days) indicates its suitability...
In this study, chitosan-gelatin-monetite (CGM)-based electrospun scaffolds have been developed that closely mimicked the microstructure and chemical composition of extracellular matrix natural bone. CGM-based nanofibrous composite were prepared with help electrospinning technique, post-cross-linked using ethyl(dimethylaminopropyl)carbodiimide N-hydroxysuccinimide solution to improve their stability in an aqueous environment. The chitosan/gelatin (CG) scaffold showed average fiber diameter...
Chitosan and monetite nanoparticles-based composite scaffold with tailored structures properties possesses tremendous potential for bone restoration. Here, we aimed to enhance the physicochemical, mechanical, biological of a three-dimensional by addition nanoparticles into chitosan matrix varying content in developed scaffolds. The scaffolds were fabricated from viscous slurry containing nano particles using free-drying process. Macro-porous incorporation nano-sized up 20 wt% total...
