EDS analysis of calcium and phosphorous atom ratios observed on the surface of CS-3, before and after immersion in PBS for 21 days.

Material	Calcium (Ca) %	Phosphorous (P) %	Ca:P Ratio
3 wt.% MCP (CS-3) before immersion in PBS (Figure 6A)	0.73	0.65	1.12
CS-3 after immersion in PBS for 21 days. Light area indicates extensive CaP precipitation (See Figure 6B–D)	31.26	19.42	1.61
CS-3 after immersion in PBS for 21 days. Dark area indicates mild CaP precipitation (See Figure 6B)	2.75	2.22	1.24
