  • In reference to the investigation of Bakshi, et al, bovine serum albumin (BSA) was found to form nanoparticles with gold (Au). BSA acts as a reducing agent by converting Au (III) into Au (0). With the application of heat, the BSA unfolds and its amino acid, cysteine, reacts with the hydrogen bonds of chloroauric acid, HAuCl4. This happens to induce the reduction of Au.
  • The agenda of this laboratory is to manipulate the two main factors, temperature and unfolding of BSA, (independent variables) that govern the formation of gold nanoparticles, AuNPs.
  • The first 3 weeks of the experiment, from August 29 to September 12, concerns the experimentation on pH and ionic strength by which temperature and concentration of chloroauric acid is tested against tris buffer at different pH levels.
