Not bullshit. microarray analysis is real and common, and existed since 1997. Actual various selected DNA fragments are on the chip itself. A multibillion dollar industry now. Its a large branch of well refined pre-programmed bioassay chip technology, and a "one time use" thing. You can use them as direct insert into humans instead of a blood drop for certain special cases. One of the first direct insert uses was to determine if a fresh corpse was murdered in bed or died in sleep. If no scratches on lower lip, or enough burst blood vessels in eyes, pre-programmed bioassay chip coded for stress chemicals (not just adrenaline) , pushed into outter brain, tell the pathologist to inform police the subject may be a muder victim. **You are correct about two things though**, pre-programmed bioassay chip technology is usually used by dropping blood on it, not inserting. Your second point is factual that the chip gets ruined from usage and is normally meant for a few minutes of testing. Held in reserve for when needed, for weeks, or years, inside and dormant, is not the same as in usage for more than one test sample. I did not click the link, I dont need to , thats how arrogant I am, and educated, but no known existant **RNA/DNA microarray analysis pre programmed chip** can withstand more that a couple exposure uses before spent. I am starting to realize that I seem to know more about the world than even wikipedia itself, the more and more tech facts I answer here on Poal.co, I dont know if its a good thing or not. Lately all I do is compute the advent of the death of the USA from socialist money printing and niggertopia on the horizon.
