Nanos (and I don't mean iPods) may detect cancer

Amazingly one of the first benefits of nanotechnology may be really, really sensitive detectors of cancer.

Harvard University researchers have
found that molecular markers indicating the presence of cancer in the
body are readily detected in blood scanned by special arrays of silicon
nanowires — even when these cancer markers constitute only one
hundred-billionth of the protein present in a drop of blood. In
addition to this exceptional accuracy and sensitivity, the minuscule
devices also promise to pinpoint the exact type of cancer present with
a speed not currently available to clinicians….

"This is one of the first applications of nanotechnology to
healthcare and offers a clinical technique that is significantly better
than what exists today," says author Charles M. Lieber, Mark Hyman Jr.
Professor of Chemistry in Harvard’s Faculty of Arts and Sciences. "A
nanowire array can test a mere pinprick of blood in just minutes,
providing a nearly instantaneous scan for many different cancer
markers. It’s a device that could open up substantial new possibilities
in the diagnosis of cancer and other complex diseases."

  1. David – I posted this nanotechnology story to Wendsight and decided to take a look at today’s FISpace next – and I see you covered this story here that I just covered in Wendsight! This is a great finding, and check out my links on my blog taking you to Nanotechnology News (if you have not visited that already!). Sarah

  2. Their whole efforts & totality is amazing,bY taking differs ideas from science studies we should get more command over all diseases like cancer etc.
