1：Experimental Design and Method Selection:
The study involved the preparation of thermochromic nanoparticles based on a leuco dye-developer-solvent system, specifically using a eutectic mixture to achieve the desired transition temperature.
2：Sample Selection and Data Sources:
The nanoparticles were synthesized using a mixture of leuco dye (TFG), developer (β-naphthol, Naph), and solvent (PEG), with varying ratios to study the effect on transition temperature.
3：List of Experimental Equipment and Materials:
The synthesis involved heating the mixture to form a thermochromic complex, followed by self-assembly in water to form nanoparticles. Characterization was performed using TEM, DLS, and UV-vis spectrophotometry.
4：Experimental Procedures and Operational Workflow:
The nanoparticles were tested for their thermochromic properties, photothermal conversion efficiency, and stability in plasma. In vitro and in vivo studies were conducted to evaluate their therapeutic efficacy and biocompatibility.
5：Data Analysis Methods:
The photothermal conversion efficiency was calculated, and the therapeutic effect was assessed through tumor volume measurement and histological examination.
