Objective

  • Continue precipitation of six large volume
  • Precipitation of 80% BSA by mass trial 3

Notes

  • The large volume precipitation were not working, after being centrifuged for 15 minutes there was no visible supernatant and when placed over the UV-light the solutions glowed evenly, which demonstrates that the precipitation was not successful. Our approach to achieve the precipitation of the ZnS QDs is to try re-centrifuging them for a longer time at a faster speed, we are only a fraction of one sample, and are storing the rest at 4 degrees Celsius.
