title = "Mesoscopic concentration fluctuations in a nanofluidic device",
abstract = "A direct consequence of downscaling fluidic devices to nanometer dimensions is that the number of molecules being detected or manipulated decreases, ultimately leading to such small numbers of analyte molecules that their discreteness and accompanying statistical fluctuations can no longer be ignored. Here we study these fluctuations both experimentally and theoretically in a nanofluidic cavity capable of detecting ~450 electrochemically active molecules. Due to Brownian motion, the average number of molecules in the device fluctuates, leading to intrinsic fluctuations in the electrochemical signal. We theoretically analyze this diffusive motion and report excellent agreement between the measured and calculated power spectrum densities without fitting parameter.",
