Fluorescence
Purpose
Use fluorescence to examine the rate at which Myoglobin templated gold nanoparticles unfold at pH 9
Procedure
- Sample was made Myoglobin: 0.25mM Au, 12.5uM Myoglobin, 3mL total
- Au 3.45mM
- (0.25mM)(3.0mL)=(XmL)(3.45mM)
- XmL= .217mL= 217uL Au
- Myoglobin 133uM
- (12.5uM)(3.0mL)=(XmL)(141.2uM)
- X=0.266mL= 266uL Myoglobin
- 30uL 1mM NaOH
- Water
- Volume of water= 3000uL- 217uL-266uL-30uL= 2467uL
- Absorbance measurements were taken and saved every 3 minutes for 3 hours
- The instrument was set at 80 degrees Celsius
- The scan range parameters were start at 310nm and ending at 540nm
- The emission and exit slit were set at 10nm
Data
Scans AuNP pH 9
Wavelength of Myoglobin AuNp's at pH 9
Maximum Intensity of Myoglobin AuNp's at pH 9
Integrated Intensity of Myoglobins AuNp's at pH 9
Solution Preparation for UV-VIS
Stock Concentrations:
- Myoglobin 141.7mM
- Silver 34.3mM
- Fructose 53.1mM
- All concentrations of fructose were redone at pH11
- All concentrations of fructose were redone at pH12
- pH 5 and 9 were repeated for 0mM Fructose
- pH 5 and 9 were repeated for 0.0625mM Fructose
Note: for pH 9 for both concentrations of fructose, 1mM NaOH was used, NOT 1M NaOH
