Abstract
Abstract Although nanoparticles are expected to revolutionize cancer treatment, their low efficacy remains the greatest limiting factor. Recent investigations found that nanoparticles' golden principle, the enhanced permeability and retention (EPR) effect, is limited by the complicated tumor microenvironment. Herein, novel transformable nanomaterials are designed to utilize the EPR effect more effectively. By tandem conjugation of the hydrophobic head (chlorin e6 (Ce6) or bilirubin (BR)), peptide to form hydrogen bond (Phe‐Phe‐Val‐Leu‐Lys (FFVLK)), and hydrophilic tail (polyethylene glycol (PEG)), chimeric molecules that can form micelles (Ce6/BR‐FFVLK‐PEG) in aqueous solution are synthesized. Notably, the spherical micelles retain shape transformability. After circulation and distribution, they respond to 650 nm laser irradiation, and morphologically change into nanofibers so as to facilitate their retention markedly inside the tumor. Upon loading a reactive oxygen species‐responsive paclitaxel dimer with thioketal linker (PTX 2 ‐TK), the resultant PTX 2 ‐TK@Ce6/BR‐FFVLK‐PEG nanomedicine serves as a potent chemo‐photodynamic therapeutic for cancer treatment. Evaluations at both cell level and animal level reveal that PTX 2 ‐TK@Ce6/BR‐FFVLK‐PEG exhibits superior biocompatibility and biodistribution, and suppresses 82.6% of in vitro cell growth and 61.8% of in vivo tumor growth at a common dose of intravenous injection (10 mg kg −1 PTX and 3.3 mg kg −1 Ce6), becoming a novel nanomedicine with extraordinary potential in cancer therapy.

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
