Remote Controlled Nanoparticles Fight Cancer

Posted December 15, 2007 8:55 AM

Injectable, functionalized nanoparticles produced by researchers at the Massachusetts Institute of Technology can be remotely triggered to release anticancer drugs. The drugs are tied to the particles using DNA strands. An applied low-frequency electromagnetic field generates sufficient heat to dissolve the DNA bonds. Because the melting point of the DNA strands can be varied, particles could be functionalized with multiple drugs or designed for cascaded release of a single drug.

Search for USPIO - magnetic particles used for imaging of cancer mets
in Nijmwegen, Netherlands and used to destroy cancers of the brain in Charite hospital, Berlin, Germany. Both experimental yet. Look for "Advanced Magnetics" they are the manufactureres of these particles.

The imaging has a factor of 4 (linear) better resolution then the other existing (radioactive labeling)methods (2 respective 8mm). A factor of 4 linear is a factor of 64 in volume so early diagnosis is giving much more time for decisionmaking and may be possibility of surgery.

The imaging possibility that was existing in Chicago was closed by the FDA and related authorities after one nonexplainable sudden death at trial.

Same was used to deny approval: ridiculous situation, severe illnesses that will be early cause of death are not allowed to test and imaged in an early stage because nobody knows if there is a certain risk or this unhappy patient died of whatever different condition.

Express your anger to your senators, may be this will help.

As I see it, they are actually looking at why that non-explained death occured and maybe see if there is a link to the high dose of magnetic radiation from the new imaging machine.

The same for these nano particles. It all sounds fantastic but we hear so many contradicting stories about what is potentially "bad" for you that I would like to see quantification of the risks and dangers of these micro electric currents causing the dna to melt inside your body. What could go wrong and what are the results of that?

I agree we need to look at this and cannot throw a blanket stop on them but there are serious implications.

Very interesting and worth further discussions.
