Beyond external labeling, some peptides exhibit intrinsic fluorescence. Research has explored non-aromatic fluorescence from single α-helical peptides, where short peptides composed of non-aromatic residues like lysine and glutamic acid can be UV active and luminescent. Furthermore, studies have investigated the intrinsic fluorescence of peptide self-assemblies, revealing how variations in factors like pH can influence their luminescent properties. This intrinsic fluorescence can be harnessed for applications without the need for external labeling.

FRET peptides are widely used for detecting the activities of proteases and protein kinases.Fluorescent peptide white paper-V1-2023 FRET, or Förster Resonance Energy Transfer, relies on the non-radiative transfer of energy between two fluorophores (a donor and an acceptor). When intact, FRET peptides quench internal fluorescence; however, the cleavage of a peptide bond between the donor/acceptor pair releases a fluorescent signal, indicating enzyme activity. This principle underpins the development of highly sensitive assaysFluorescent Peptides: Valuable Tools for Medical Research.

Fluorescent- and biotin-labeled peptides are also invaluable tools in biochemistry, finding numerous applications in enzymology and protein chemistry. The ability to label peptides with both a fluorophore and biotin allows for versatile detection and purification strategies. Moreover, peptide-based fluorescent probes leverage the biocompatibility and programmability of peptides to specifically target tumor cells, thereby facilitating high-resolution imaging and diagnosis.
