Subject: Could we combine metals and drugs...

Hi, I searched the archives and couldn't find anything about this.  I'm sorry 
if this question has been asked already.  I was just reading some material on 
chelating agents that can trap metal ions from water.  I was wondering if this 
principle can be applied to medicine/drugs.  Could we somehow combine a certain 
drug with a metal, inject it into a blood stream, and use magnets outside the 
body to guide the drugs to a specific area of interest?  On second thought I'm 
not sure if you'll want to inject metals into the body, but is this idea 
feasible?  Thanks for your time
