ObjectiveSynthesize two different sets of gold nanoparticles. In one set, Au3+ is reduced by a protein (bovine serum albumin, BSA) and the synthesized nanoparticle is also surrounded and stabilized by BSA. In the second set, Au3+ is reduced by citrate, and the AuNP is stabilized by citrate in solution. The BSA-AuNPs are purple in color and the citrate-AuNPs are more of a burgundy (reddish) color.

ProcedurePart 1: BSA-AuNP Synthesis
Part 2: Citrate-AuNP Synthesis

Matt Hartings In the future, your spectra are going to be much easier to read if they only have lines (and no symbols). Calculations from Part 2
Observations
Matt Hartings based on this final volume (and initial concentration) what is your concentration of gold?
