Abstract
Abstract An innovative approach is presented for the synthesis of gold photothermal agents tailored for Near Infrared light NIR‐I and NIR‐II photothermal applications using bottlebrush polymers (BB) as soft templates (BB@Au). Upon exposure to NIR‐I, ( λ ex = 808 nm) and NIR‐II ( λ ex = 1064 nm) light, the photothermal agents (BB@Au) exhibit robust photothermal effects, achieving temperatures up to 58.3 °C under 500 mW cm −2 NIR‐II laser irradiation. This remarkable thermal response enables efficient eradication of cancer cells in both 2D and 3D settings. Furthermore, comprehensive studies demonstrate the biocompatibility of BB@Au, as evidenced by concentration‐dependent and time‐dependent analyses. Studies conducted with zebrafish larvae further confirm their safety, showing no abnormalities in hatching, survival, and histology sections. Aside from their enhanced photothermal effects, the BB@Au significantly enhances the Raman signal of adsorbed analytes. This allows their quantification and broadens the potential applications of the BB@Au particles as substrates for small molecules biosensing. The bottlebrush‐based approach to produce novel gold nanostructures with augmented photothermal capabilities introduces a versatile strategy for developing precise and effective photothermal agents in a one pot process.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
