John J. Kasianowicz from NIST and his colleagues created a 2D method for mass spectrometry capable of a single-molecule analysis based on the interaction between a nanometer-scale pore and analytes. The method is a “nano” version of Wallace Coulter patented technique that detects particles suspended in solution by driving them …

The researches inadvertently discovered that they can write and erase on the surface of liquids - the method that could one day be applied to high-density data storage, making templates for etching silicon chips (photolithography) and a variety of …
