Polycatenane‐based nanocarriers. A) Synthesis and preparation of cyclodextrin (CD)‐based polycatenane. B) Absorbance peak change of 2‐nitro‐5‐thiobenzoic acid and C) thiol content change after treating the prepared polycatenane with H₂O₂. D) Schematic release of CD from polycatenane under redox environment. E) Nanoparticle size distribution, F) GPC profiles, and G) release profiles of polycatenanes before/after treatment with DTT.
