„Die Außenhülle des Mikroroboters, welche aus Graphen besteht, fängt das Blei ein”, sagt Sanchez, Gruppenleiter am Max-Planck-Institut für Intelligente Systeme in Stuttgart und am Institute for Bioengineering of Catalonia (IBEC) in Barcelona. „Die innere Platinschicht funktioniert als Antrieb und zerfallendes Wasserstoffperoxid als Treibstoff, sodass der Roboter sich selbst antreiben kann.“

“The outer shell of the microbot, which is graphene, captures the lead,” says Samuel, group leader at the Max-Planck Institute for Intelligent Systems in Stuttgart and the Institute for Bioengineering of Catalonia (IBEC) in Barcelona. “The inner layer of platinum works as the engine, decomposing hydrogen peroxide as fuel so that the bot can self-propel.” When hydrogen peroxide is added to the wastewater, the platinum decomposes it into harmless water and oxygen bubbles, which are ejected from the back of the microbot to propel it forward. “It’s important to use a system of pollutant removal that doesn’t produce any additional contamination," explains Samuel.
