Provided are devices and methods for polymer analysis, in which labeled polymers are translocated along nanochannels that have illuminated detection regions within. As a labeled polymer translocates along the nanochannel and the labels pass over the illuminated detection regions, the labels become detectable (e.g., where different labels fluoresce in response to different wavelengths present at different illumination regions), and the user generates a spatial map of the location of the various labels along the length of the polymer. The location of the labels is then correlated to one or more structural characteristics of the polymer. 1. An analysis device , comprising:a plurality of nanochannels running along the surface of a first substrate, each nanochannel defined by side walls and a floor; andat least one nanoslit being disposed in a second substrate, the nanoslit being disposed such that electromagnetic radiation of at least a first wavelength passing through the nanoslit defines, within the at least one nanochannel, an illumination region having a cross-sectional dimension smaller than the first wavelength.2.
