説明
<jats:title>Abstract</jats:title><jats:p>Enzyme catalysis to power micro/nanomotors has received tremendous attention because of the vast potential in applications ranging from biomedicine to environmental remediation. However, the current design is mainly based on a complex three‐dimensional (3D) architecture, with limited accessible surface areas for the catalytic sites, and thus requires a higher fuel concentration to achieve active motion. Herein we report for the first time an enzyme‐powered 2D nanobot, which was designed by a facile strategy based on soft nanoarchitectonics for active motion at an ultralow fuel concentration (0.003 % H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>). The 2D nanobots exhibited efficient positive chemotactic behavior and the ability to swim against gravity by virtue of solutal buoyancy. As a proof‐of‐concept, the 2D nanobots showed an excellent capability for “on‐the‐fly” removal of methylene blue (MB) dye with an efficiency of 85 %.</jats:p>
