Fig. 6. Micro photographic view of blood cells treated with different concentration of citrate and green AuNP along with negative and positive control samples. Deformations are indicated by white arrows. Blood cells treated with (A) PBS (B) low concentration (0.25 μL mL⁻¹) of citrate stabilized AuNP (C) high concentration (5.0 μL mL⁻¹) of citrate stabilized AuNP (D) low concentration (0.25 μL mL⁻¹) of green AuNP (E) high concentration (5.0 μL mL⁻¹) of green AuNP. Negative control sample treated with SDS shows complete haemolysis without any residual blood cells. Here, only low and highest treatments are shown as indicative.
