“…The indole-5,6-quinone (IQ) in PDA is a conjugated structure, and the D-A structure is formed between the 5,6-dihydroxyindole (DHI) and IQ units, so it has photothermal conversion performance in the NIR range [95,96]. There are many active functional groups on PDA with good photothermal properties and biocompatibility, so it is easily modified to be used in PTT [96][97][98][99][100]. When using simple PDA as the PTA, there are some problems, including easy aggregation, which results from a large number of active groups, thereby reducing light absorption efficiency, and uneven heat distribution to bacteria [101].…”

Photothermal therapy has the advantages of non-invasiveness, low toxicity, simple operation, a broad spectrum of antibacterial ability, and non-proneness to developing drug resistance, which provide it with irreplaceable superiority in fighting against microbial infection. The effect of photothermal therapy is closely related to the choice of photothermal agent. Conjugated nanomaterials are potential candidates for photothermal agents because of their easy modification, excellent photothermal conversion efficiency, good photostability, and biodegradability. In this paper, the application of photothermal agents based on conjugated nanomaterials in photothermal antimicrobial treatment is reviewed, including conjugated small molecules, conjugated oligomers, conjugated polymers, and pseudo-conjugated polymers. At the same time, the application of conjugated nanomaterials in the combination of photothermal therapy (PTT) and photodynamic therapy (PDT) is briefly introduced. Finally, the research status, limitations, and prospects of photothermal therapy using conjugated nanomaterials as photothermal agents are discussed.

“…With this perspective, a one-component, waterborne polyurethane (WPU)/PDA monolithic polymer matrix produced by coating the surfaces of each WPU particle with the PDA layer while they were in the dispersion state has been presented in our previous publication . The prepared product presented an easily applicable, monolithic hybrid material in the form of a one-component and subjected to different publications for varied targets. − The mentioned study presented a photothermal material that can be used in various related applications, but it was not focused on the superiority of the preparation method over the classical approaches.…”

Polydopamine (PDA) is an attractive material utilized for a wide range of scientific purposes, including light-tothermal energy conversion, because of presenting plenty of advantages. The proper integration way of PDA into a system is critical to benefit from the PDA content in maximum. Here, the two main PDA-containing composite preparation methods were compared in terms of fundamental material properties and the light-to-thermal energy conversion ability of the final product. For this purpose, the classical emulsion polymerization method first synthesized an aqueous dispersion of polystyrene nanoparticles (PS). PDA was then integrated into the system via two different preparation methods: coating the surfaces of polystyrene nanoparticles with a PDA layer while PS is in a dispersion state (PS@PDA) and adding separately synthesized PDA nanoparticles into the PS dispersion medium (PS−PDA). Two prepared composite systems were fundamentally characterized by dynamic light scattering (DLS), ultraviolet−visible (UV−vis) spectroscopy, and scanning electron microscopy (SEM) while in their dispersion state, and by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier-transform infrared (FTIR) spectroscopy, and X-ray diffraction (XRD) while in their solid state, which was obtained after the water evaporated. As the targeted property, the solid forms of these were investigated in terms of light-to-thermal energy conversion performance with solar and laser light exposure under 1 SUN and at 808 nm, respectively. The results showed that the composite system prepared by coating surfaces of PS nanoparticles with the PDA layer had higher light-to-thermal energy conversion under both conditions than those prepared by separately added PDA nanoparticles into the dispersion system. To show one of the possible applications of the prepared composites, in addition to the main target, the solid form of the composite system, which was prepared by coating surfaces of PS nanoparticles with the PDA layer, was also evaluated in detail concerning the latent heat-storage ability with incorporation of PEG 4000 as a phase-change material (PCM) into the system. It was found that the prepared shape-stable phase-change composite with a ratio of 1:3 between PS@PDA and PEG 4000 resulted in a latent heat of 126.9 J/g.
