Figure 3From: Quantification of calcium content in bone by using ToF-SIMS–a first approach ToF-SIMS data from standards and rat bone. a) Schematic graph of the ToF-SIMS analysis of trabecular bone. b) Positive ion mass spectrum of a mineralised scaffold showing the expected HAP fragments up to high masses [24]. c) Linear dependence of the normalized Ca-signal intensity from the HAP content of the scaffolds. Linear fit and the linear equation are shown. d) Summary of the Ca quantification results for different groups and different times after osteoporosis induction in rats.Back to article page
