“…45 The typical peaks at about 1293, 1470, and 1558 cm −1 correspond to the stretching vibration of benzenoid C−N and the CC stretching mode in benzenoid and quinonoid units, respectively. 46 The bands at about 790 and 695 cm −1 are due to the out-of-plane deformations of the C−H bending vibration, 47,48 and the peak at about 500 cm −1 belongs to the CC out-of-plane bending vibration. 49 The peaks belonging to PANI occur in the FT-IR spectrum of 4% PANI/SnS 2 , suggesting that PANI is contained in this composite.…”

A series of polyaniline (PANI)-decorated SnS2 nanoplates (PANI/SnS2) were produced via a hydrothermal method followed by a liquid–solid mixing. The PANI/SnS2 nanocomposites were composed of amorphous PANI and hexagonal-phase SnS2 nanoplates. Infrared thermal images revealed that PANI had an excellent near-infrared (NIR)-induced photothermal effect. Overall, the PANI/SnS2 nanocomposites showed better NIR-enhanced electrocatalytic and photoelectrocatalytic hydrogen evolution activity than bare SnS2 nanoplates. The optimized 4% PANI/SnS2 (which contained 4 wt % PANI) displayed the largest electrochemical double-layer capacitance (C dl) value (0.85 mF cm–2) and the lowest Tafel slope of 66 mV dec–1 in 0.5 M H2SO4 under NIR irradiation. It was investigated and confirmed that the photothermal effect and the synergistic effects between SnS2 and PANI heterostructure played important roles in promoting electrocatalytic and photoelectrocatalytic hydrogen evolution processes.

“…In this paper, we propose a temperature monitoring system based on PID feedback on the photoacoustic-photothermal effect of tissue under the action of graphene oxide. We used graphene oxide in photothermal therapy with high photothermal conversion performance and low cytotoxicity [18] to establish a linear relationship between the amplitude of the photoacoustic signal and temperature in the process of photothermal treatment of tissues from the change of photoacoustic signal and temperature. The change of tissue temperature was monitored by monitoring the change of tissue photoacoustic signal to reach the change of tissue temperature, and the output power of the heated continuous laser was adjusted according to the temperature change by PID algorithm, so as to monitor and regulate the tissue temperature.…”

Tissue local temperature information is necessary for guiding treatment parameters in photothermal therapy. Therefore, a temperature monitoring method suitable for the treatment process is needed for monitoring tissue temperature in real time. In this study, a temperature monitoring system based on PID on the photothermal effect of graphene oxide on tissue was proposed. Graphene Oxide (GO) has high photothermal conversion performance and low cytotoxicity under near infrared laser irradiation at 808nm. The photoacoustic imaging system and infrared thermal imager were employed to monitor the effect of GO as a photothermal agent on the photoacoustic signal and temperature of tissues. Firstly, the relationship between the intensity of photoacoustic signal and the temperature of tissues under the action of GO was established. Then, the PID feedback algorithm was applied to monitor and regulate the temperature change of tissues by the intensity of photoacoustic signal, so as to achieve the purpose of photothermal treatment. The results show that GO can enhance the photoacoustic signal of the tissue under laser irradiation and improve the temperature of the irradiated tissue. The system can effectively monitor and regulate the tissue temperature to achieve the therapeutic effect of tumor with little effect on normal tissue.

“…In addition, the tumor cells are more sensitive to damage from hyperthermia because the absorbance of NIR laser by the human body is very low. [1,2,6,[8][9][10][11][12][13] Moreover, NIR laser can be easily operated to adjust NIR laser power and focused on minimal areas where the photothermal agents are released which means heat can uniformly and rapidly be distributed to tumor cells. Additionally, PTT is suitable to be combined with other methods to improve treatment synergistically.…”

In this work, superparamagnetic Fe3O4@PPy nanocomposite with core‐shell structure having strong near‐infrared (NIR) absorption is synthesized via a facile two‐step modified procedure. The prepared nanocomposite samples are characterized by UV–vis, FTIR, SEM, TEM, VSM, and XRD. The effects of laser power density (1.5–2.5 W cm−2) and aqueous concentration (0.01–0.2 mg ml−1) of the nanocomposite on the photothermal performance are investigated in the NIR region (808 nm). At 0.1 mg ml−1 concentration, the temperature reaches up to 50.1°C, 64.1°C, and 78.4°C within 10 min, under 1.5 W cm−2, 2.0 W cm−2, and 2.5 W cm−2 NIR laser power density values, respectively. Photothermal conservation efficiency is calculated as 43.9% and the nanocomposite exhibits excellent photothermal stability. In summary, the core‐shell Fe3O4@PPy nanocomposite is a promising candidate for photothermal therapy and simultaneous magnetic field‐guided treatments.
