The sound waves passing through that sensor can then be compared with an uncoated control crystal: Differences in the waves mean the chip has picked up trace amounts--as little as a few trillionths of a gram--of the target substance. Alone nano-oscillator produces signal strengths of only trillionths to billionths of a watt. In addition, since the extreme ultraviolet laser produces light pulses with very short duration (4 picoseconds, or trillionths of a second), the researchers believe it may be possible to create picosecond-scale snapshots of important processes in other applications. |
