Abstract Over the past decade, significant advancements in micro‐nano robots have enabled non‐invasive operations hazardous, confined environments, particularly targeting persistent bacterial biofilms hard‐to‐reach areas. However, many of these are limited by poor magnetic properties, hindering their effectiveness against biofilms. This study proposes a novel strategy using swarm with strong effects (Hercules swarm) combined near‐infrared (NIR) light for effective biofilm eradication. Carbonyl iron particles coated polydopamine (CI@PDA), averaging ≈3 µm diameter, demonstrate clustering and magneto‐force under rotating field due to large saturation. enables Hercules achieve rapid delivery (100 mm s −1 ), efficient cargo transport (carrying twice its own weight), catheter clearance (1 min ). The controllable motion high photothermal activity enable precise eradication without toxic agents. aggregation into chains rotation explored improved particle dynamic model. Simulations also reveal enhanced fluid convection mechanical pressure around chain. Due easy operation, straightforward controllability, environmental compatibility, emerges as promising treatment modality eliminating entrenched within intricate, narrow, convoluted medical implants or industrial conduits.

Nano-/microrobots have been demonstrated as an efficient solution for environmental remediation. Their strength lies in their propulsion abilities that allow active “on-the-fly” operation, such pollutant detection, capture, transport, degradation, and disruption. Another advantage is versatility, which allows the engineering of highly functional solutions a specific application. However, latter can bring complexity to applications; versatility dimensionality, morphology, materials, surface decorations, other modifications has crucial effect on resulting abilities, compatibility with environment, overall functionality. Synergy between decorations its projection functionality object nanoarchitectonics. Here, we scrutinize nano-/microrobots eyes nanoarchitectonics: list general concepts help assess synergy limitations individual procedures fabrication processes operation at macroscale.
