Cotton-wool-like sol-gel glass from electrospinning

Researchers have combined sol-gel processing with electrospinning to produce cotton-wool-like CaO-SiO2 glass structures.  The cotton-wool-like morphology was attributed to the rheological properties of the electrospinning solution causing branching of the primary jet and to fibre regions rich in calcium ions creating bending instabilites in the applied electric field.  The material was moldable and could be packed into complex bone defects.  Preliminary results suggested the materials were bioactive and non-cytotoxic.
