Procedure

  • Luminol --> final concentration such that A(330)< 1.
  • Hydrogen peroxide --> final concentration to be 50x luminol concentration
  • HRP --> 60:1 Au:HRP solutions, 100 μL
  • Buffer --> add up to 3 mL

In cuvette, luminol, buffer, and hydrogen peroxide

  • Start kinetics by adding HRP
  • What percent of HRP is still active?

Control:

  • experiment with BSA-AuNPs and citrate-AuNPs
  • what concentration of AuNPs about the same (use absorption spectra)

Data

A1V1 = A2V2 (0.3)(100 μL)=A2(3 mL) A2 = ?
