Characteristics of ZER-ICG @DMNs patches. (A) SEM images of ZER-ICG@DMNs array. (B,C) The EDS elements mapping and content of ZER-ICG@DMNs. These elements were labeled with corresponding colors. (D) Force–displacement profiles of the MNs (n = 5). (E) SEM-imaged of ZER-ICG@DMNs, ZER@DMNs, ICG@DMNs, and Blank @DMNs tip morphologies after compression; (F) Drug content of ZER-ICG@DMNs patches at above terms (n = 3). (G) Morphological structure of ZER-ICG@DMNs patches in various states (RT, 4℃ for 7, 14, 28 days).
