Abstract Gold nanoparticles (NPs) are promising for cancer therapy due to their versatile shapes, optical properties, adjustable sizes, and facile functionalization. However, diverse physicochemical complex in vivo environments, cellular heterogeneity lead markedly different interactions with cells, impacting reproducibility application selection. To address this, we implemented a DNA barcoding system label gold NPs varying surface modifications tumor delivery optimization. Six NP species, comprising three shapes (sphere, rod, triangle) two sizes (40 nm, 80 nm), were tagged unique barcodes. Barcodes demonstrated minimal detachment, no interference cell interactions, resistance DNase digestion. Next‐generation sequencing revealed that sphere exhibited poor vitro uptake but superior targeting, likely enhanced endothelial reduced macrophage clearance. Additionally, nm nanotriangles displayed excellent targeting both vivo. Supporting experiments validated these findings. demonstrate practical utility, the applied siRNA photothermal breast model. This study pioneers integration of systematically explore shape, size, delivery.
