Chlorella-Based Biohybrid Microrobot for Removing Both Nutrient and Microalgae toward Efficient Water Eutrophication Treatment

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
