Ultrathin and biocompatible heating systems offer several advantages in thermotherapy and thermal imaging applications. Here, we report a biocompatible, ultrathin, and optically activated single-wall carbon nanotube (CNT) coated silk nanofiber (SNF) heating system. The CNT/SNF membrane heater showed a broadband absorption in the UV–Vis range that was intrinsic to metallic CNTs in the sample. The photothermal properties of the CNT/SNF membranes have been studied with different illuminating wavelengths. The membrane heater showed significant heating behavior with the maximum temperature rise of 67 °C when illuminated with the wavelength of 532 nm and with the optical power of 45 mW. The temperature rises and decay constants for the heating systems were extracted to be 10.2 and 5.9 s at an illuminating wavelength of 532 nm, respectively. The faster heating and cooling behaviors emphasize their potential applications in thermotherapy and biomedical imaging.

超薄且生物相容的加热系统在热疗和热成像应用中具有多项优势。在这里，我们报告了一种生物相容性、超薄和光学激活的单壁碳纳米管 (CNT) 涂层丝纳米纤维 (SNF) 加热系统。CNT/SNF 膜加热器在 UV-Vis 范围内显示出宽带吸收，这是样品中金属 CNT 固有的。已经用不同的照射波长研究了 CNT/SNF 膜的光热性能。当以 532 nm 的波长和 45 mW 的光功率照射时，膜加热器显示出显着的加热行为，最大温升为 67 °C。在 532 nm 的照明波长下，加热系统的温升和衰减常数分别为 10.2 和 5.9 秒。
