  • Observe under the microscope.
  • Sonicate each samples.
  • Fluorescence of samples with dyes already attached were measured by using fluorometer.

Part 2

  • 0.3 g of sample with and without lecithin placed in to 2 different vials.
  • Add 6ml of water and sonicate the samples.
  • Take 1 ml of each sample add in to 1.5ml microcentrifuge tubes. Centrifuge samples.( Additionally pipette it up and down to break the larger pieces.)
  • Add 1μl of R6G to each microcentrifuge tubes to be absorbed by the PVOH.
  • Fluorescence of samples with dyes already attached were measured by using fluorometer.
