Catalytically powered dynamic assembly of rod-shaped nanomotors and passive tracer particles
Open accessAbstract
Significance: Microscale catalyst particles suspended in fluids can convert the energy of chemical reactions that occur on their surfaces to movement. Collections of particles undergoing powered motion exhibit behavior that mimics living microparticles such as bacteria: swarming, predator–prey interactions, and chemotaxis. These behaviors originate from pairwise interactions of particles that so far have not been measured or understood. In this article, short-range attractive interactions of catalytic nanorod motors were shown to arise from electrical forces. These forces drive the transient formation of dimers and trimers, and are also responsible for the collection of passive tracer particles at the ends of the nanorods. The quantitative description of these interactions lays the theoretical groundwork for understanding and manipulating the collective behavior of nanomotors.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
