Abfero Pharmaceuticals Inc.Logo Design Contest

We develop new drugs that remove iron (Latin symbol for iron is "Fe") from the body in disease situations where excess iron is a problem.

Blue and green seem to work best for healthcare. However, we are dealing with drugs that address iron in the body and blood so maybe some red or purple might work. I wonder if we could consider "Fe" in a red/purple as part of the Abfero logo. We might consider spelling the word Abfero as "AbFero" where the Fe is red or purple (but I'm not completely convinced of this).

Summary:
I probably want 3 colors maximum for the logo itself.
I like Blue and green for healthcare but iron is associated with blood and is red/purple so we might consider this.
We can spell Anfero with or without a Capital "F"
We like the concept of wrapping or encapsulating iron (see Sideris Logo)

"Fe" is the symbol for iron which is the basis for our drugs. We bind iron so some imagery that shows "Fe" being encapsulated by parts of the logo could be good. We could try making the "fe" of Abfero capitalized i.e. AbFero. Please see another logo that was done for an earlier company that had the same target ie. binding of iron. In Sideris we used the concept of the logo encapsulating a central "ball" that represented the iron being bound. Some similar concept could be interesting.
