Abstract: Methods of imaging a 2D sheet are provided. In embodiments, such a method comprises illuminating a sample with light having a wavelength 1, the sample comprising a quenching substrate; a transparent, non-quenching 2D sheet on the quenching substrate; and a fluorescent layer comprising fluorescent dye molecules on the transparent, non-quenching 2D sheet and the quenching substrate, providing background domains and 2D sheet domains in the sample, wherein the light induces fluorescence of the dye molecules in the fluorescent layer. The method further comprises detecting fluorescence from the sample to provide an image of the transparent, non-quenching 2D sheet, wherein an intensity IB of the detected fluorescence from the background domains is less than an intensity I2DSs of the detected fluorescence from the 2D sheet domains, thereby providing contrast in the image.
