A complex nanofluidic device consisting of a slit embedded with an array of nanopit cavities is used to study the physics of confined DNA. By measuring the number of cavities occupied by a molecule in varying geometries, the entropic free energy of confinement and effective molecular width were measured. By measuring the correlation time of contour fluctuations between two pits, the dependence of the dominant relaxation modes on the local free energy landscape was investigated. By measuring the fraction of a molecule occupying single pits of varying size, the effects of excluded volume interactions in cavities were studied. The results were considered in light of a model for the free energy of confinement taking into account semi-flexibilit...
