a TEM image of gelatin-AgNPs synthesized at 90°C ( C _gelatin : 0.4 wt%, $V_{{\text{AgNO}}_3}$ : 2 mL); b XRD of gelatin-AgNPs power obtained from the sample in a; c TEM image of gelatin-AgNPs synthesized at 90°C ( C _gelatin : 0.4 wt%, $V_{{\text{AgNO}}_3}$ : 4 mL). AgNO ₃ was added in gelatin solution in two times. At first, 0.2 mL AgNO₃ was added. The other AgNO₃ was added into reaction mixture after 10 h.
