Abstract
Nanomechanical resonators are explored as mass sensors and molecular sensors due to their high sensitivity and real time label-free detection ability, respectively. One downside of mechanical molecular sensing is the lack of chemical information carried in the signal. For this reason, a secondary technique such as functionalized surface, gas chromatography, or photothermal spectroscopy, must be combined with mass sensing for chemical specificity. As an alternative to this approach, we have developed a metallized nanomechanical resonator, capable of electrical local heating. Here, we explore the use of local temperature as a secondary molecular indicator similar to thermogravimetric analysis. In the present study, we explore the desorption of a polymer from these electrical nanostring sensors above room temperature and the adsorption of acetone below room temperature.
