    • An alternative approach to the realization of self-assembled chemosensors, called "chemosensing ensemble", has been proposed and involves the displacement of a non-covalent dye-receptor complex by the substrate.

    • note
    • In the hypothesis of a homogeneous distribution of the subunits, the quenching of 20% of the dyes implies that 20% of the particle surface area is the quenching "dominion" of the Cu(II) ions. A single particle (radius 9 nm) contains about 7000 subunits and hence 140 ligand units.
