## Nanoparticle Fiber

• Determine the concentration and amounts needed for Au and BSA in a solution with 140 times more Au than BSA
• Concentrations:
• Au = .25 mM
• BSA = 1.785 μM
• Amounts:
• Au = .4924 mg
• BSA = 1.19 mg
• Amounts needed multiplied by 10 to get 10 times the concentration in stock solutions
• Theoretical Amounts:
• Au = 4.924 mg
• BSA = 11.9 mg
• Actual amounts used:
• Au = 5.3 mg
• BSA = 12.6 mg
• Adjusted mL based on extra amounts:
• Au solution = 10.76mL
• BSA solution = 10.57mL
• 1mL was siphoned from each solution and added to 8mL of purified water.
• The 10mL Au+BSA+H2O solution was then put into the oven for approximately 4 hours.

## Gel

• 10mL of water was added to 1.682 g poly(vinyl alcohol) (130,000 molecular weight)
• This solution was heated and stirred for approximately 40 minutes until a homogeneous gel remained
