Congratulations to Dave

A recent editorial in the Saturday, March 30/2013, issue of the Winnipeg Free press details the research by a local physicist for his discovery of using spectroscopy for detecting bacteria in food products , as well as in humans especially those residing in personal care homes. In the interview many practical uses for this technique were outlined  mentioning also  that such a procedure would also shorten the diagnostic period currently required by food inspectors. I want to congratulate the physicist whom I know personally for this discovery. I hope Dave that you have better success in your application than I did, maybe patenting would have helped me.
Here is my experience. 
While employed with the department of Cancer Research at the University of Saskatchewan in the 1960's I outlined a quantitative procedure to screen for cancer. The rationale for the test is as follows. Since all normal human cells have the same number and kind of chromosomes, namely 22 pairs of autosomes or body chromosomes and one pair of sex chromosomes (XX in the female and XY in the male), and since the DNA of a cell is restricted to the chromosomes and further since the Feulogen stain is specific for DNA , then all  non dividing  normal human cells have the same amount of DNA.We call this the 2C amount. Cancer cells on the other hand are heteroploid i.e. they either have  abnormal numbers and/or kinds of chromosomes, and will therefore have abnormal amounts of  DNA (deviation from the 2C amounts).The reader should refer to the publications in Acta Cytologica 1969 for more details.Because this is  a quantitative screening procedure it not only had the potential of being automated, but more importantly  it eliminates the subjective component associated with the current cyto-pathological  diagnosis -the so called Pap test.
Unfortunately no company has seen fit to commercialize this  2 wave length DNA cytophotometry quantitative procedure for cytodiagnosis of cancer and/or a rapid screening procedure.
