  bibo_abstract:
  - Catalytic microswimmers convert the chemical energy from fuel into motion. They
    sustain chemical gradients and fluid flows that propel them by phoresis. This
    leads to unconventional behavior and collective dynamics, such as self-organization
    into complex structures. Characterizing the nonequilibrium interactions of microswimmers
    is crucial for advancing our understanding of active systems. However, this remains
    a challenge owing to the importance of fluctuations at the microscale and the
    difficulty in disentangling the different contributions to the interactions. Here,
    we show a massive dependence of the nonequilibrium interactions on the shape of
    catalytic microswimmers. We perform tracking experiments at high throughput to
    map interactions between nanocolloidal tracers and dimeric microswimmers of various
    aspect ratios. Our method leverages dual tracers with differing phoretic mobilities
    to quantitatively disentangle phoretic motion from hydrodynamic advection. This
    approach is validated through experiments on single chemically active sites and
    on immobilized catalytic microswimmers. We further investigate the activity-driven
    interactions of free microswimmers and directly measure their phoretic interactions.
    When compared to standard models, our findings highlight the important role of
    osmotic flows for microswimmers near surfaces and reveal an enhanced contribution
    of hydrodynamic advection relative to phoretic motion as the size of the microswimmer
    increases. Our study provides robust measurements of the nonequilibrium interactions
    from catalytic microswimmers and lays the groundwork for a realistic description
    of active systems.@eng
