Nano-Particles Could Manufacture Cancer-Killing Drugs Inside
Your BodyS  MIT researchers have built a nano-scale, drug-
producing factory that could provide precision cancer tumor-
killing inside your body.  Drugs made of proteins are good at
killing cancer tumors, but the human body in turn is good at
killing foreign proteins that show up our bloodstream. So
protein drugs have trouble reaching their destination. But the
nanoparticle created by the MIT researchers would get around
that by not synthesizing the protein until it reaches the tumor.
They showed in their study, which is published in the journal
Nanoletters that they could induce the particle to deploy its
payload by shining an ultraviolet light on it.  "This is the
first proof of concept that you can actually synthesize new
compounds from inert starting materials inside the body," said
Avi Schroeder a postdoc in MIT's David H. Koch Institute for
Integrative Cancer Research and a lead author on the work.  The
tiny drug factory mimics the way DNA instr
