The morphology and the electronic conductive properties of self-assembled monolayers formed by helical oligopeptides suitably functionalized with electro- and photoactive units were investigated by electrochemical, spectroscopic and atomic force microscopy techniques. The versatility of peptide building blocks was also highlighted by the formation of bicomponent self-assembled monolayers exploiting interchain dipole–dipole interactions.
Theranostic agents based on nanovectors (liposomes, naposomes, micelles, polymeric micelles and micelles built around a solid core) able to carry, simultaneously, a drug and a contrast agent and externally modified with targeting peptides are described.
