Experimental Biological Chemistry I

Au/ADA samples made on 2012/11/27 were ran on UV-vis spectrophotometer and Atomic Absorption Spectrometer, results were analyzed.
Au/ADA samples were resuspended in a range of Tris buffers to test resuspension based on concentration of buffer and pH.

3mL of Au/ADA samples with the following mole ratios were analyzed using UV-vis spectrophotometer.

  60-70-80-90-100-110-120-130-140-150

3mL of distilled water was run on UV-vis under spectrum method. The absorbance obtained from wavelength range 200nm to 800nm were used as base line correction for the Au/ADA samples.
