Abstract

An augmented strategy for constructing intelligent soft robots includes the transfer of biogenic features from nature to man-made artificial systems serving a range of life-like functions. Inspired by living technology, we have customized macroscale hydrogel boats by encoding them with an enzyme-powered engine that can convert chemical information into a mechanical response to create motion at the air-water interface. The engine's non-homogeneous enzyme distribution causes erratic motion along straight lines, random turns, and turns with high or low curvature-like trajectories. Nevertheless, the structural remodeling of the boat as well as the working system's configuration can permit directed, controlled, turning, bi-directional, rotation and run-and-tumble-like motion. Intriguingly, this boat is capable of sensing the precise chirality of amino acids (D-amino acid vs.L-amino acid) from individual isomer samples by translating the chiral information into variations in the boat's speed. Therefore, such miniaturized enzyme-powered boats are anticipated to be an advantage for the upcoming next-generation materials with a broader spectrum of functionalities.

酶驱动的大尺度凝胶船的可编程运动：功能传感平台。

构建智能软机器人的增强策略包括将生物特征从自然界转移到服务于一系列类生命功能的人造系统。受生活技术的启发，我们定制了宏观尺度的水凝胶船，用酶驱动的引擎编码它们，可以将化学信息转化为机械反应，在空气-水界面产生运动。发动机的非均匀酶分布导致沿直线的不稳定运动，随机转弯，以及高或低曲率轨迹的转弯。然而，船的结构改造以及工作系统的配置可以允许定向、控制、转弯、双向、旋转和奔跑和翻滚运动。有趣的是，这艘船能够通过将手性信息转化为船速的变化，从单个同分异构体样品中感知氨基酸的精确手性（d -氨基酸和l -氨基酸）。因此，这种小型化的酶动力船有望成为下一代具有更广泛功能的材料的优势。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
