Circular dichroism confirms efficient transfer of chirality from the amino acid backbone to the supramolecular assemblies. At the same time, atomic force microscopy reveals distinct stereochemical control: L\u2010forms generate nanospherical structures, while D\u2010forms produce nanoconical morphologies. The conjugates exhibit strong dansyl\u2010based fluorescence with highly selective turn\u2010off responses toward Hg(II), following Stern\u2013Volmer behavior with micromolar detection limits; Job's plot and morphology variations support metal\u2010induced reorganization.
