  For CitrateAuNP the UVVis was used to analysze the solution. With the results found, it could be analyzed using [http://pubs.acs.org/doi/suppl/10.1021/ac0702084/suppl_file/ac0702084si20070321_014144.pdf this reference]. It had a maximum absorbancy of .031at 520 λ. The absorbance at the wavelength 450 was 0.02. The particle size in our solution was 12 nm. This was found by dividing the two absorbencies mentioned above and locating the number on the chart from the link. With knowing the particle size, the molar absorbtivity was found. It was 1.09E<sup>+8</sup>. USing the formula Concentration= Absorbance at 450/ Molar Absorbtivity at 450. The concentration of gold and citrate in the diluted solution was 1.83 x 10 <sup>10</sup>M.

ResultsFor CitrateAuNP the UVVis was used to analysze the solution. With the results found, it could be analyzed using this reference. It had a maximum absorbancy of .031at 520 λ. The absorbance at the wavelength 450 was 0.02. The particle size in our solution was 12 nm. This was found by dividing the two absorbencies mentioned above and locating the number on the chart from the link. With knowing the particle size, the molar absorbtivity was found. It was 1.09E^{+8}. USing the formula Concentration= Absorbance at 450/ Molar Absorbtivity at 450. The concentration of gold and citrate in the diluted solution was 1.83 x 10 ^{10}M. The stock concentration was 9.17 x 10 ^{8}M.
