Purpose

  • To resuspend gold nano-particle pallets with Tris buffer.
  • To determine the best concentration and pH of Tris buffer for resuspension via measuring the absorbance of resuspended solutions throughout time.
  • To make new sets of Au/BSA solutions with varies ratios.

Procedure

  • A new sets of solutions of BSA and HAuCl4 mixture were made. New stock solutions of HAuCl4 and BSA were also made.
  • The old sets of solutions of Au/BSA at different ratios were...

Notes

  • The new sets of solutions made on 2012/09/04 failed to react. The solutions after heating appeared yellow in color. This indicates the BSA failed to react with the HAuCl4 in solution.
