Weighing Molecules using a MEMS sensor! Researchers from French lab CEA-Leti produced a mass sensor with 170zg resolution for weighing molecules. For context, 1zg (Zeptogram) equals to 10 raised to -21 grams!
The device has been designed for use inside the vacuum of a mass spectrometer to detect neutral particles.
