LAT and neoplasm: developed a bioinspired leucine‐decorated photosensitizer (CP‐PLeu) that enables efficient mild‐hyperthermia PTT (mPTT) through homogeneous tumor accumulation and photoactivated reversal of tumor thermoresistance for minimally invasive breast cancer treatment (Figure 12c).[295] CP‐PLeu self‐assembled into biomimetic nanoclusters with leucine‐rich outer layers that facilitate rapid and uniform tumor accumulation through L‐type amino acid transporters (LAT) recognition.
