Combination of different therapy modalities with multiple tumoricidal mechanisms has emerged as a promising anticancer strategy. Herein, we reported an aldehyde/catechol-functionalized hyaluronic acid (DAHA) and hydroxyethyl chitosan (HECS) decorated gold nanorod (GNR) platform for combined chemo-photothermal therapy of breast cancer.
