What was done

Today we analyzed our gold nanoparticles solutions using atomic absorption

Notes

Table 1. Standard Au Solution preparation from 1000μg/mL AA Au gold standard solution

Concentration(μg/mL) Volume of stock Au solution(mL) Volume Deionized water added(mL)
10 0.1 9.9
20 0.2 9.8
30 0.3 9.7
40 0.4 9.6
50 0.5 9.5

Au:Lysozyme Ratio Appearance of solution Au:Hemoglobin Ratio Appearance of solution
5 Colorless 30 Lightly colored
10 Lightly colored 50 Lightly colored
15 Colored darkly 70 Darkly colored
20 Colored 90 Darkly colored
25 Colored 110 Colorless
30 Colored 130 Colorless
35 Colored 150 Colorless
40 Colorless 170 Colorless
