“…The NIR lights have been of huge interest in many areas such as photo-thermal ablation, laser-assisted medical therapy and night vision sensing. [30][31][32] However, until now there're scarce published works taking advantage of PDA's chromatic transition to detect the NIR lights. The light-toheat conversion ability of dyes has been extensively utilized in the NIR lights induced cationic polymerization of epoxides and the free polymerization of acrylates.…”

Due to the unique optical and chromatic properties toward various external stimuli, conjugated polydiacetylene (PDA) materials are attracting a great attention from scientists. And the fabrication of PDA embedded composites would further expand the application prospect. In this work, aniline substituted diacetylene derivative was embedded into wax matrix to form a writable composite. After UV induced 1,4-topochemical polymerization, the patterns generated from the PDA/wax composite showed clearly a blue-to-purple-to-red colorimetric change upon thermal stimulus. More interestingly, with the introduction of two representative near-infrared (NIR) dyes to the composite, the PDA also showed blue-to-red chromatic transition in response to distinctive NIR lights irradiation.

“…Nanoparticles were prepared for controlled drug delivery, with particle size and thermoresponsive behavior dependent on copolymer length and concentration. These results demonstrate the feasibility of using PVCL microgels as templates and stabilizers at high temperatures and offer novel synthesis strategies for hybrid microgels applicable in various fields of nanotechnology, including catalysis, sensing, and therapy [ 133 , 134 , 135 , 136 , 137 ].…”

It is shown that a more than significant amount of experimental data obtained in the field of studying systems based on thermosensitive hydrophilic polymers and reflected in the literature over the past decades makes the issue of their systematization and classification relevant. This, in turn, makes relevant the question of choosing the appropriate classification criteria. It is shown that the basic classification feature can be the number of phase transition stages, which can vary from one to four or more depending on the nature of the temperature-sensitive system. In this work, the method of inverse phase portraits is proposed for the first time. It was intended, among other things, to identify the number of phase transition stages. Moreover, the accuracy of this method significantly exceeds the accuracy of the previously used method of direct phase portraits since, for the first time, the operation of numerical differentiation is replaced by the operation of numerical integration. A specific example of the application of the proposed method for the analysis of a previously studied temperature-sensitive system is presented. It is shown that this method also allows for a quantitative comparison between the results obtained by the differential calorimetry method and the turbidimetry method. Issues related to increasing the resolution of the method of direct phase portraits are discussed.

“…As shown in Figure 1, the classification of PTAs can be broadly divided into inorganic PTAs and organic PTAs. Among them, inorganic PTAs mainly include noble metal nanoparticles (gold nanorods, 36–38 gold nanocrystals, 39 gold nanostars, 40 gold nanoshells 41,42 ), carbon nanomaterials (graphene, 43 carbon nanotubes 44,45 ), and other inorganic nanoparticles (black phosphorous, 46,47 MoS 2 48–50 and silica, 51 and so on). Organic materials include organic dyes (indocyanine green [ICG], 52 Prussian blue 53 ) and polymer nanoparticles (such as polypyrrole, 54,55 semiconducting polymer nanoparticles 56 ).…”

Photothermal therapy (PTT) has been regarded as a promising strategy considering its advantages of high inherent specificity and a lower invasive burden. Since the photothermal killing of cells/bacteria showed different patterns of death depending on the varying temperature in PTT, the temperature change of PTT is vital to cell/tissue response in scientific research and clinical application. On one hand, mild PTT has received substantial attention in the treatment of cancer and soft/hard tissue repair. On the other hand, the high temperature induced by PTT is capable of antibacterial capacity, which is better than conventional antibiotic therapy with drug resistance. Herein, we summarize the recent developments in the application of temperature-dependent photothermal biomaterials, mainly covering the temperature ranges of 40-42°C, 43-50°C, and over 50°C. We highlight the biological mechanism of PTT and the latest progress in the treatment of different diseases. Finally, we conclude by discussing the challenges and perspectives of biomaterials in addressing temperatureorchestrated PTT. Given a deep understanding of the interaction between temperature and biology, rationally designed biomaterials with sophisticated photothermal responsiveness will benefit the outcomes of personalized PTT toward various diseases.
