New method of DNA testing promises to transform medical diagnostics
...s what makes the test sensitive. It is capable of collecting a large number of photons. The ability of the polymer to absorb and emit a photon relative to the ability of that small florescent molecule attached to the PNA tail is huge, and that is what we call 'optical amplification.'
