The construction of erasable and rewritable superhydrophilic–superhydrophobic patterns on novel TiO 2 nanotube arrays is described by Y. K. Lai, C. J. Lin, L. F. Chi, and co‐workers on page 2945 . The patterned superhydrophobic surface is an excellent 2D scaffold for site‐selective cell adhesion and reversible protein absorption, and acts as a template to deposit or grow well‐defined 3D spatially functional biomaterials (e.g., CaP, Ag, biological molecules, and drugs). Furthermore, the functional composite patterning allows specificity for SERS sensors, antibacterial agents, targeted drug delivery and cell bioassays.
