Summary
Tissue-engineering scaffolds work best when they are both biologically active and made from sustainable, biocompatible materials. This study brings together two such components in a single electrospun fibre: soy protein, an inexpensive, plant-derived biopolymer that supports cell attachment, and bioactive glass, an inorganic material that bonds to bone and stimulates tissue regeneration through the ions it releases. The authors electrospin soy-protein/bioactive-glass composite fibres and characterise the resulting non-woven mats, examining fibre morphology and the incorporation of the glass phase. The fibrous architecture mimics the extracellular matrix while the bioactive glass adds osteo-stimulatory function — a combination aimed at scaffolds for both soft- and hard-tissue engineering, and an example of pairing a natural protein with an inorganic bioactive filler.
