摘要: A contrast-amplifying carrier for observing a sample, includes a transparent substrate bearing at least one absorbent coating suitable for behaving as an antireflection coating when it is illuminated at normal incidence at an illumination wavelength λ through the substrate and when the face of the coating opposite the substrate is in contact with a medium referred to as a transparent ambient medium, the refractive index n3 of which is lower than that of the refractive index n0 of the substrate. The absorbent coating comprises: an absorbent sublayer referred to as the contrast sublayer, deposited on the surface of the transparent substrate; and an absorbent layer referred to as the sensitive layer, distinct from the contrast sublayer and comprising between 1 and 5 sheets of a graphene-type material. Methods for producing and for using such a contrast-amplifying carrier are also provided.

摘要: A method is provided for positioning a micro- or nano-object on a planar support by displacement performed under visual control, wherein the micro- or nano-object is immersed in a transparent medium, called ambient medium, having a refractive index n3; the planar support comprises a transparent substrate of refractive index n0>n3 on which is deposited at least one optically absorbent layer, adapted to behave as antireflection coating when it is lit at normal incidence with a lighting wavelength λ through the substrate; and the visual control comprises the lighting of the micro- or nano-object at least with the wavelength λ through the substrate, and the observation thereof also through the substrate. A method to scanning probe microscopy and to the assembly of nanostructures is provided.
