Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Multicompartment, spherical microcontainers were engineered through a layer‐by‐layer polyelectrolyte deposition around a fluorescent core while integrating a ruthenium polyoxometalate (Ru₄POM), as molecular motor, vis‐à‐vis its oxygenic, propeller effect, fuelled upon H₂O₂ decomposition. The resulting chemomechanical system, with average speeds of up to 25 μm s⁻¹, is amenable for integration into a microfluidic set‐up for mixing and displacement of liquids, whereby the propulsion force and the resulting velocity regime can be modulated upon H₂O₂‐controlled addition.</p> </abstract>
