You can basically have a metal detector that's the size of a badge or a gas detector that's a little larger than the button on your shirt.

I've got to admit there are a lot better sensors already on the market, but you might end up spending $400,000, and you'd have to have a pickup (truck) to carry them around. You get to a point where you say, how much better than good do I need to be?

Natural gas is a feedstock in basically every industrial process.

I associate heavy metal with fantasy because of the tremendous power that the music delivers.

I have metal in my body, so every time I go to an airport, the metal detector goes off.

The size compatibility between the detector and the detected species-DNA molecules in this case-makes this approach very attractive for further development of label-free electronic methods.
