TNT: Silicon microcantilevers modified with a three-dimensional layer of vertical titanium dioxide nanotubes (see picture) can be used in micromechanical sensors with optical signal detection to detect low levels of explosives such as 2,4,6-trinitrotoluene (TNT) in the gas phase, even in the presence of other volatile impurities such as n-heptane and ethanol.
