Abstract Silk degumming is considered the first point in preparation of silk-based materials since this process could modify silk fiber and properties its related products. This study evaluated differences morphology, secondary structure, amino acid content, thermal stability, mechanical two types raw materials, defective cocoons (DC) fibrous waste (SW), degummed by chemical (C) autoclaving (A) methods. Subsequently, fibroin films were prepared dissolving each type fibers, structural...
In this work, the effect of fabrication parameters on silk fibroin (SF) nonwovens obtained by electrospinning were evaluated. Additionally, relationship between secondary structures and thermal stability protein materials, with morphological characteristics analyzed. Silk in formic acid solution at 10% w/w was electrospun 8 cm varying ratio voltage/distance flow rate. The morphology observed Scanning Electron Microscopy (SEM) fibers diameter determined ImageJ software. changes structure...
Abstract Enhancing the biocompatibility and mechanical stability of small diameter vascular scaffolds remain significant challenges. To address this challenge, small‐diameter tubular structures were electrospun from silk fibroin (SF) textile industry discarded materials to generate bilayer that mimic native blood vessels, but derived a sustainable natural material resource. The inner layer was obtained by directly dissolving SF in formic acid, while middle (SF‐M) achieved through aqueous...
RESUMEN El procesamiento de fibroína seda (SF) por medio la técnica electrohilatura ha abierto un amplio campo posibilidades para generar membranas fibrilares a escala micro y nanométrica, que aunados las propiedades biocompatibilidad destacadas mecánicas esta proteína, potencian su uso en diversas aplicaciones ingenieriles biomédicas. Los procesos se encuentran sujetos una gran cantidad variables interacciones entre ellas, lo cual vez repercute morfológicas del material obtenido. En el...
