Structue of thene nanometer thick membrane with different functional groups on each side was fabricated from self‐assembled monolayers of aromatic molecules. The amino side of this Janus membrane was modified with tetramethylrhodamine (TMR) fluorescent dye, and the thiol side with ATTO647N. A fluorescence micrograph is seen to the right.

(a) Schematic representation of the fabrication of nanosheets and their transfer onto arbitrary substrates. A self-assembled monolayer of BPT is cross-linked by electron irradiation (1). The resulting nanosheet can be released from the substrate (2) and transferred to solid substrates (3) or over the openings of a grid (4). (b) Optical micrograph of a large piece of nanosheet transferred onto a Si wafer containing a 300nm thick layer of native SiO2. (c) Nanosheet spanned over the openings of a TEM grid. (d) AFM image of the edges of a transferred nanosheet, the corresponding line scan shows a sheet thickness of ∼1nm.
