Schematic illustration of fabrication process and adsorption of the tetrapeptide Ac-DEVD-CHO. Amorphous alumina was deposited by atomic layer deposition onto as-grown CNT arrays and then either further processed by annealing at 950°C within an oxygen atmosphere or Ac-DEVD-CHO was directly absorbed onto the amorphous alumina NW array. After burn-out of the CNTs and production of polycrystalline alumina NWs, Ac-DEVD-CHO was similarly absorbed onto the polycrystalline NW array before cell culture.
