Tasklist
- Prepare reducing agent stock solutions
- 5 - 10 mL of 100 mM each
- fructose, galactose, sucrose, Na3Ct, H2Asc

- For cellulose nanocrystals, use a 4% solution
- 1 mg NaBH4 in 20 mL ice cold H2O. Do NOT cap!!
- AuNP for 100 mM stock solutions
- 0.1 mL 10 mM HAuCl4 + 0.1 mL 100 mM reducing agent + 3.8 mL H2O
- For cellulose, add 0.1 mL 10 mM HAuCl4 to 3.9 mL cellulose
- 0.2 mL 10 mM HAuCl4 + 3.8 mL NaBH4
- Place test tubes in water bath (600 mL beaker) at 80 C until color changes (~30 min)
- Measure UV-VIS of your solutions
