AbstractSmall organic photothermal agents (SOPTAs) that absorb in the second near‐infrared (NIR‐II, 1000–1700 nm) window are highly desirable in photothermal therapy for their good biocompatibility and deeper tissue penetration. However, the design of NIR‐II absorbing SOPTAs remains a great challenge. Herein, we report that molecular engineering of BF2

The synthesis of photothermal carbon/hydroxyapatite composites poses challenges due to the binding modes and relatively low photothermal conversion efficiency. To address these challenges, the calcium ions chelated by photothermal carbon dots (PTC-CDs) served as the calcium source for the synthesis of photothermal carbon dots chelated hydroxyapatite ...

Photothermal conversion efficiency of nanofluids: An experimental and numerical study [PDF]
Solar Energy, 2016 This work investigated experimentally the photothermal conversion efficiency (PTE) of gold nanofluids in a cylindrical tube under natural solar irradiation conditions, which was also compared with a developed 3-D numerical model. The PTE of gold nanofluids was found to be much higher than that of pure water, and increased non-linearly with the ...
