Moving Forward
Here is a list of different ideas I am going to pursue through the end of the semester.


 * calculate force on single ferritin w/ magnetization
 * conjugating ferritin to quantum dots
 * fluorescent ferritin
 * other types
 * double check the "broken" yoke
 * George Church
 * Jeromy Edwards
 * "salad dressing"
 * Search through the literature
 * resistance and current on electromagnet
 * quantum dots: magnetic?
 * liposome

Fluorescent Ferritin
I was able to find a paper about fluorescent labeled ferritin. Here is |the link on ScienceDirect.

Some things that I learned:
 * Ferritin has lysine and cysteine residues on the external surface that can be used for tags. The authors used the lysine to attache fluorophores.
 * Adding the fluorophores increases the water solubility of the protein.
 * Steve Koch 18:30, 22 April 2010 (EDT): Good find on this article! I, too, thought they claimed fluorophore increased water solubility, which seemed weird to me.  Then upon reading the introduction, I think they mean that ferritin makes the iron oxide more soluble than just plain iron oxide.  That would make sense, since ferritin is supposed to be a soluble protein, and lysine residues help with solubility.
 * They mentioned something called a magnetometer with a SQUID sensor that I want to look up.
 * The iron core was not altered by labeling the ferritin.
