## Objective

Making new catalase and Hb AuNP samples, as described here for AA and UVVis analysis.

## Description

1. HAuCl4
1. 24.6mg
2. 25.0 mL water
2. Hemoglobin
1. 15.2mg
2. 10.0 mL water
3. Catalase
1. 40.8mg
2. 10.0 mL water

I made HbAuNP samples similar to this procedure. Also, there are two ways to think about the ratio of Au:Hb. Hb is a tetramer. So, the molar mass is either 16125 (for the monomer) or 64500 (for the tetramer). The ratios listed below are for the tetramer/monomer. The ratios as reported in the referenced notebook page are those for the monomer.

1. Au:Hb Ratio = 30
1. 500uL gold
2. 1766uL Hb
3. 2734uL water
2. Au:Hb Ratio = 50
1. 500uL gold
2. 1059uL Hb
3. 757uL water
3. Au:Hb Ratio = 70
1. 500uL gold
2. 757uL Hb
3. 3743uL water
4. Au:Catalase Ratio = 90
1. 500uL gold
2. 589uL Hb
3. 3911uL water
5. Au:Catalase Ratio = 110
1. 500uL gold
2. 482uL Hb
3. 4018uL water
6. Au:Catalase Ratio = 130
1. 500uL gold
2. 407uL Hb
3. 4093uL water
7. Au:Catalase Ratio = 150
1. 500uL gold
2. 353uL Hb
3. 4147uL water
8. Au:Catalase Ratio = 170
1. 500uL gold
2. 312uL Hb
3. 4188uL water
9. Au:Catalase Ratio = 190
1. 500uL gold
2. 279uL Hb
3. 4221uL water
10. Au:Catalase Ratio = 210
1. 500uL gold
2. 252uL Hb
3. 4248uL water

In order to get a more detailed view of the Catalase trends I made the following solutions:

1. Au:Catalase Ratio = 7
1. 500uL gold
2. 2556uL catalase
3. 1944uL water
2. Au:Catalase Ratio = 17
1. 500uL gold
2. 1096uL catalase
3. 3404uL water
3. Au:Catalase Ratio = 26
1. 500uL gold
2. 697uL catalase
3. 3803uL water
4. Au:Catalase Ratio = 36
1. 500uL gold
2. 511uL catalase
3. 3989uL water
5. Au:Catalase Ratio = 46
1. 500uL gold
2. 404uL catalase
3. 4096uL water
6. Au:Catalase Ratio = 55
1. 500uL gold
2. 333uL catalase
3. 4167uL water
7. Au:Catalase Ratio = 65
1. 500uL gold
2. 284uL catalase
3. 4216uL water
8. Au:Catalase Ratio = 74
1. 500uL gold
2. 247uL catalase
3. 4253uL water
9. Au:Catalase Ratio = 84
1. 500uL gold
2. 219uL catalase
3. 4281uL water
10. Au:Catalase Ratio = 93
1. 500uL gold
2. 197uL catalase
3. 4303uL water

I also took UVVis of the gold, Hb, and catalase stock solutions.

For each, I measured the spectrum for a 10X dilution of each stock solution.
