Here, we constructed nanoparticles (MP5L@DOX), which are self‐assembled from 1‐methyl‐tryptophan (1‐MT)‐perfunctionalized pillararene conjugated with a lactose‐derived ligand, with DOX encapsulated within the supramolecular architecture to enable receptor‐mediated cellular uptake and pH/esterase dual‐responsive drug release. The multivalent display of 1‐MT on the pillararene …
