A cicada wing has a biocidal feature of rupturing the membrane of cells, while the cactus spine transmit a water drop to the stem. These properties have evolved from their respective unique structures. Here, we endeavor to develop bioinspired nanohairs that mimic the cicada‘s wing-like vertical hairs and the cactus spine-like stooped hairs. It was found that the neuroblastoma cells on the vertical hairs showed significantly decreased proliferation. It was also found that the behavior of cells on stooped nanohairs is strongly influenced by the direction of the stooped nanohairs. Consistent with these results, the vertical and stooped structures can facilitate the control of cell viability and guide directional migration for biomedical applications. |
