John McDevitt developed the LabNow device to read nano-bio-chips that will look for signs of oral cancer and other diseases. The painless, non-invasive test requires just a light brush of the lesion on the cheek or tongue with an instrument that looks like a toothbrush. Preliminary studies found that the test was 97 percent “sensitive” and 93 percent specific in detecting which patients had malignant or premalignant lesions.

RICE (US)—A test that uses a new diagnostic nano-bio chip is as effective and far more expedient in detecting oral cancer than traditional invasive lab procedures. Continue…

Nanotubes + ink + paper = instant battery
STANFORD (US)—Dip an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, and it turns into a battery or supercapacitor. Crumple the piece of paper, and it still works. (more…)

Tiny tweezers snag living cells
While optical tweezers are large and expensive, acoustic tweezers are smaller than a dime, small enough to fabricate on a chip using standard chip manufacturing techniques. They can also manipulate live cells without damaging or killing them. Above, the interdigital transducers (yellow) emit surface acoustic waves that push particles into position.

Faster than supersonic on ‘spiked’ jet fuel
“The idea of being able to put in a very small quantity and have such a dramatic effect is important,” says lead investigator Ilhan Aksay about adding nanocatalysts to jet fuel to improve performance.

Nanoalerts from healthy cells signal cancer
Vadim Backman, the study’s senior author, says nanoscale changes in both cancer cells and normal cells far away from the tumor site “are general phenomena in carcinogenesis and occur early in the process.”

Making room to manufacture tiny bio-devices
UC IRVINE (US)—The next generation of miniature devices built from sensitive organic materials may be coming from specialized manufacturing facilities, like the new clean room lab at the University of California, Irvine. Scientists at the facility are able to work at a scale that is one-hundredth the diameter of a human hair. (more…)
