Single-molecule mass spectrometry

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 through a capillary which is […]

Liquids as Future Data Storage

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 other materials applications. Peter Licence at the University of Nottingham, UK, and his colleagues were using […]
