Electrospun Poly(γ-glutamate)/Silica Hybrids for Tissue Regeneration: Influences of Silane Coupling Agents on Chemistry, Degradation and Florescent Dye Release : Figure 4

Figure 4: Percentage Si and Ca release of elements contained in fibre mats after soaking in a buffer solution.O-2G and O-4G showsa burst of Si and Ca release at12 h after soaking, whereas P-2G shows a gradual Si release and smaller burst of Ca release.
