Objectives

  1. Prepare Heme and BSA solutions in petri dishes
  2. Prepare some samples for XRD analysis


Preparation of samples for XRD analysis

  • Small portions of magnetite sample were dried from the samples prepared on 02/19/2014


General Protocol for sample drying from petri dish samples:

  1. Using a transfer pipette, pipette approximately 2mL of sample from petri dish.(This sample should include at least 1mL of black/brown particulate)
  2. Place sample in a clean and dry 10mL vial.
  3. Place the uncapped vial in a fume hood for ~24 hours or until sample is completely dry


  • All 10 samples were placed in the fume hood to dry for future analysis


Sample preparation

Notes

  • Methods for quantitative magnetic analyses must be determined for future analysis of the prepared magnetic nanoparticles. Particularly, the alignment of the magnetic fields of all the nanoparticles is necessary for the quantitative analysis of the nanoparticles. Possible methods for analysis include:
  1. NMR analysis (1H longitudinal (R1) relaxation)- This will create a uniform magnetic field
  2. Magnetometer
