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.
