Eyeing Explosives with Raman Spectroscopy

Posted January 03, 2008 8:21 AM

Explosives can be detected and identified using Raman scattering spectroscopy. It detects changes of vibrational energy level states when scanned by an eye-safe laser. Chemical bond vibrations within the molecule furnish a 'fingerprint' based both on the material composition and the molecular structure of each constituent. Are there real time applications in industry?

UV enhanced Raman Spectroscopy could be used to detect counterfeit drugs at every entry port in the world.

Counterfeit drugs are killing people worldwide and cause untold suffering. Physicians, pharmacists and medical personnel are unable to recognize clever counterfeited packaged prepartions from authentic drugs.

Counterfeiters have excellent skills and equipment at their disposal and produce millions of bogus doses of medication every year. Detection at the consumer level would help to put an end to this criminal activity.

You are right.

I have a plan to manufacture very special equipment for this purpose using IMS and also IR Optical Spectrometers with software library for chemicals. It is also a big business. We can collaborate. Interested?

Keep in mind that often the counterfeit drugs are actually the real deal, just watered down to a much lower dosage than advertised. A 10% dose gets 90% more profit (or thereabouts) and yet is still the same real drug. Just likely ineffective for the patient.

Perhaps you are more inspired by the work of Dr. Samuel Hahnemann

but here point is that people also use real high concentration drugs and some of them are made with lots of impurity that may be really poison and not medicine any longer. Spectroscopy is sure a great tool to know about atoms and molecules and molecular interaction in complex matrix of which drug is actually made of.

Some chemicals are unwanted and some are really required so both types need to be monitored and put into specifications. After all drugs are highly specified chemicals and they are certified to be what they are granted permission to be used on human body.

We can not talk about some arbitrary benefit and if some one get benefited and want to use medicine on others in that way then have to prove that to others to become acceptable.

You don't have to prove that salt or sugar is acceptable but let the cook to add too much or too little or change it to something else then you will feel like kicking the person right in the public.

When it comes to drugs, we believe in life and death relationship of a person and extreme knowledge utilization from medical science to human kind and it is not some kind of joke to be accepted in public. Everything whatever it may be must come thorough thoroughly evaluated scientific tests.

I am not at all familiar with Dr. Hahnemann - for what it's worth, I concur with all you said. My only point is that counterfeit drugs are not always a different substance, sometimes just a lesser concentration of the real drug, and detecting that is likely to be a more complex problem (although not an insoluble one).

I enjoyed your comment about kicking the cook in public...
