Excessive nutrients and explosive growth of harmful microalgae in water environments are key challenges in the treatment of eutrophication. The development of a low-cost, time-saving, and small-space-suitable research method that can simultaneously remove nutrients and microalgae is highly anticipated. This work first proposed applying microrobots to eutrophication treatment. Phosphate and (. ) were selected as representative nutrients and harmful microalgae, respectively, to investigate the efficient removal effect of the microrobots on the two. The Chlorella@FeO@ZIF-8 biohybrid microrobot can not only perform the dual removal of phosphates and . but also take advantage of its small size and controllable motion to achieve targeted treatment of eutrophication of water in microenvironments such as microchannels, thereby achieving the effect of fundamentally treating the eutrophication. The Chlorella@FeO@ZIF-8 microrobot reveals a new strategy for the treatment of eutrophication and also exploits a new perspective for application research of microrobots.
水环境中过量的营养物质以及有害微藻的爆发式生长是富营养化治理中的关键挑战。人们高度期待能开发出一种低成本、省时且适用于小空间的研究方法，该方法能够同时去除营养物质和微藻。这项工作首次提出将微型机器人应用于富营养化治理。分别选择磷酸盐和（此处原文缺失具体内容）作为代表性营养物质和有害微藻，以研究微型机器人对二者的高效去除效果。小球藻@FeO@ZIF-8生物杂交微型机器人不仅能够实现对磷酸盐和（此处原文缺失具体内容）的双重去除，还能利用其体积小和运动可控的特点，实现对微通道等微环境中水体富营养化的靶向治理，从而达到从根本上治理富营养化的效果。小球藻@FeO@ZIF-8微型机器人揭示了一种治理富营养化的新策略，也为微型机器人的应用研究开拓了新视角。
