a Synthesis procedure and TEM image of ZnO-CNP-TRGL; b Photothermal images for control media and ZnO-CNP-TRGL (25, 50, 100, and 1000 nm) suspensions (50 µg mL−1) with different irradiation times (0–5 min) at 2 W cm−2; c Illustration images for the size transformation of ZnO-CNP-TRGL from hydrophilic dispersion and hydrophobic micrometer aggregation; LCST is lower critical solution temperature.
