The fluorescent and photochemical properties of PDs are considered and the potential of application of these compounds as probes/sensors for biomolecular systems is assessed. In particular, interactions of cationic PDs with DNA and other biomolecules and those of anionic and cationic PDs with proteins, as well as the applicability of PDs as sensors in biomicellar systems and the application of molecular docking in studies of the interaction of PDs with biomolecules are discussed.

Compositions of mixtures for co-immobilization of lactate oxidase and mediators (potassium hexacyanoferrate(<span>iii</span>) or hexaammineruthenium(<span>iii</span>) chloride) in a chitosan membrane were developed. An increase in both the chitosan content (up to 0.1 vol.%) in the mixture and the signal registration time (up to 10–15 s) helped to expand the linear range of the test strips into the region of high lactate concentrations (up to 30 mmol L<sup>−1</sup>). The applicability of the test strips for the lactate concentration determination in whole blood matrix was demonstrated, and the prospects for non-invasive lactate detection in sweat were considered.
