Abstract

A smart bilayer of AG@CNT/AG composed of carbon nanotubes (CNTs) and agarose (AG) is developed. TiO₂ patterns which partly reflect light are introduced at the bilayer surface, giving rise to a spatially selective photothermal effect that can be used to induce shape-programmed motility upon light irradiation. The TiO₂ patterns also result in the bilayer with a differential flexural modulus and can thus modulate its motility induced by humidity.
