Abstract: 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 2 O 2 ). 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 %.

Abstract: The controlled spatial organization or compartmentalization of multi-enzyme cascade reactions to transfer a substrate from one enzyme to another for substrate channeling on scaffolds has sparked increasing interest in recent years. Here, we use graphene oxides to study the dependence of the activity of cascade reactions in a closely packed, randomly immobilized enzyme system on a 2 D scaffold. We first observe that the hydrophobicity of graphene oxides and various enzyme architectures for co-immobilized systems are important attributes for achieving high product-conversion rates. A transient time close to 0 s can be achieved if enzymes are randomly immobilized close to one another, owing to direct molecular channeling. This contributes to overcoming complications regarding control of the spatial arrangement of the enzymes. Furthermore, a fabricated bienzyme paper can be used for glucose detection with high stability, reusability, and enhanced substrate channeling. Our findings provide new guidance for enzyme orientation on 2 D scaffolds, which may be extrapolated to other multienzyme cascade systems.

Abstract: Supramolecular architecture-based truly “pH taxis” exhibiting nanomotors are fabricated by in-situ grown CaCO 3 particles, which can sense the endogenously present pH gradient in HeLa cells making them suitable for targeted drug delivery applications.
