A new article in Nature Biotechnology (abstract) describes
… highly sensitive, label-free, multiplexed electrical detection of cancer markers using silicon-nanowire field-effect devices …
built into arrays. As the article about the paper on medicalnewstoday.com discusses, the sensitivity and accuracy of this technology is supposed to be phenomenal. The potential of this is incredible — routine blood tests for cancer! This would make it much easier to catch cancer early, before it does irreversible damage, reducing not only the expense, but also the mortality of cancer occurrences.
As Nature is not an open access journal, I unfortunately have yet to actually read the paper. I might have had access to it via Tulane, but since their servers are still down, I don’t. Would anyone care to send me a pdf?
