Abstract Amphiphilic peptides have garnered significant attention due to their highly designable and self‐assembling behaviors. Self‐assembled hold excellent potential in various fields such as biosensing, environmental monitoring, drug delivery, owing remarkable biological, physical, chemical properties. While nanomaterials formed by peptide self‐assembly found widespread use biomedical applications, the development of 2D nanosheets based on amphiphilic remains challenging terms rational design morphology modulation. In this study, rationally designed molecules are self‐assembled into (PNS) under specific conditions encapsulate gold nanoparticles (AuNPs), resulting formation AuNPs/PNS hybrid materials with high photothermal conversion efficiency. The findings demonstrate that PNS enhances overall therapy effect nanohybrid larger hosting area for AuNPs higher biocompatibility. well‐designed study offer insights structural functional modulation molecules. addition, constructed biomimetic‐functional inorganic/organic applications engineering.
