The strong photothermal effect made by the combination of localized surface plasmon resonance (LSPR) presented by gold nanorods (AuNRs) with polydopamine (PDA) makes them appeal nanomaterials for biomedical applications. Here, by seed-mediated growth and a further self-polymerization of dopamine (DA), a reproducible hybrid nanoplatform combining these two materials have been synthesized (AuNRs/PDA). PDA shell thickness was controlled as well as LSPR, besides, their effect on temperature and the photocatalytic response was examined towards Rhodamine 6G (Rh6G) degradation showing a final depletion of 51% during 60 minutes of irradiation and a catalyst concentration of 7.4 µg mL<sup>-1</sup>. Moreover, the kinetics of the reaction were studied through the Langmuir-Hinshelwood model which in combination with time-resolved spectroscopy, and finite-element method simulations of plasmons unveiled low thermalization and enhanced charge carrier at the composite resulted from the combination of AuNRs plasmons and low thermal conductivity presented by PDA [1].<br/><br/>1.
