(a) Force plotted against deflection (micrometer) for two Si cantilevers, C1 and C2, with and without a DND coating. (b) Dynamic response (expressed in millivolts) of a DND-coated cantilever before exposure to DNT and following exposure to 0.27 and 5.23 ppm DNT vapor exposure.
Static mode characterization—spring constant values determined from Fig. 1.
Dynamic mode characterization for the Si cantilevers with and without DND coatings, giving resonant frequency values and shifts, mass loading, and particle density.
Shift in resonant frequency for DND coated Si cantilevers after 2,4 DNT exposure.
