A Harvard-led team of engineers have developed a two by two millimeter spectrometer that is considered the smallest device that is capable of performing multidimensional nuclear magnetic resonance (NMR) spectroscopy.
The engineers shrunk the electronic components to place them on a silicon chip smaller than the size of a sesame seed. The miniscule design maintains the functionality of larger spectroscopy systems allowing the systems to be portable and used in locations with size restrictions. In addition to NMR spectroscopy, the chips could be used with a larger superconducting magnet for other applications.
