In order to maintain thermal comfort in the human body, photothermal conversion and energy storage microcapsules were designed, developed, and applied in a light-assisted thermoregulatory system. The octyl stearate as a phase change material (PCM) was encapsulated using a polytrimethylolpropane triacrylate (PTMPTA)/polyaniline (PANI) composite as the shell, which was synthesized by adding the intermediate half oxidation state of PANI into the polymerization system of trimethylolpropane triacrylate (TMPTA). In the PCM microcapsules, the PANI particles embedded in the shell can convert sunlight into heat energy to feed the PCM core for energy storage, further realizing the temperature regulation and solving the problem that the phase change behavior cannot be triggered in cold environments. The octyl stearate@PTMPTA/PANI microcapsules exhibit a latent heat of over 103 J/g, good thermal reliability, and 89.12% photothermal conversion efficiency (PCM microcapsules (MEPCM) suspension). Owing to the excellent photothermal performance of the PANI, the thermal energy will be generated under sunshine and simultaneously transferred to the microcapsules for energy storage. As a result, the MEPCM-PTMPTA/PANI can not only achieve a higher temperature than ambient air but also initiate the phase transition process. The obtained microcapsules were further printed on a T-shirt, and a test of self-thermoregulation was carried out in winter. The results suggest that MEPCM-PTMPTA/PANI has good photothermal conversion and temperature regulation capacity under sunshine and low temperature environments.

“…So, mild PTT is often combined with other therapies for synergistic effects instead of being used alone 108 . In the previous study, PTT‐chemotherapy, 109–111 PTT‐PDT, 112,113 PTT‐immunotherapy, 114 PTT‐radiotherapy (RT) 115,116 and PTT‐gene therapy (GT) 65,117–119 were widely studied. At the same time, through further exploration of the molecular mechanism of tumor cells, other advanced strategies have been developed to improve the anticancer efficiency of PTT at mild temperatures, such as HSP inhibitors, 120,121 autophagy regulation agents, 122 and targeting enhanced strategy 123–125 …”

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.

“…They have been investigated for applications as sensors, photocatalysts, bioimaging agents, drug and gene delivery systems, and most recently in chemo-photothermal therapy (chemo-PTT) for cancer treatment. − Gold nanostructured materials are the leading nanomaterials used in PTT and photothermal-triggered drug release . Other inorganic nanostructures such as iron oxide, copper sulfide, , BiAgOS nanoparticles, mesoporous organosilica, titanium carbide derivates, pegylated-SiO x /CeO 2 /VO x , and cobalt oxide nanoparticles have also been frequently used in biomedical applications. However, low stability, long-term toxicity, and high cost have drastically limited their diffusion in PTT.…”

Carbon-based nanostructures are attracting a lot of attention because of their very low toxicity, excellent visible lighttriggered optical and photothermal properties, and intriguing applications. Currently, the development of multifunctional carbon-based nanostructures for a synergistic chemo-photothermal approach is a challenging topic for the advancement of cancer treatment. Here, we report an unprecedented example of photoresponsive carbon-based polymer dots (CPDs-PNM) obtained by a one-pot thermal process from poly(N-isopropylacrylamide) (PNIPAM) without using organic solvent and additional reagents. The CPDs-PNM nanostructures were characterized by spectroscopic techniques, transmission electron microscopy, and atomic force microscopy. The CPDs-PNM exhibited high photothermal conversion efficiency, lower critical solution temperature (LCST) behavior, and good cytarabine (arabinosyl cytosine, AraC) loading capacity (62.3%). The formation of a CPDs-PNM/AraC adduct and photothermal-controlled drug release, triggered by green light excitation, were demonstrated by spectroscopic techniques, and the drug−polymer interaction and drug release mechanism were well supported by modeling simulation calculations. The cellular uptake of empty and AraC-loaded CPDs-PNM was imaged by confocal laser scanning microscopy. In vitro experiments evidenced that CPDs-PNM did not affect the viability of neuroblastoma cells, while the CPDs-PNM/AraC adduct under light irradiation exhibited significantly higher toxicity than AraC alone by a combined chemo-photothermal effect.
