From Coffee Rings to Self-Driven Assembly: Active Matter Enabled Design of Drying Droplets

Meneka Banik, Ranjini Bandyopadhyay

Active particles in drying droplets generate self-driven flows that override the coffee ring effect for controlled assembly.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Systems containing motile microorganisms, chemically active colloids, or externally driven particles can continuously inject energy or generate gradients within the droplet, leading to self-driven flows, modified interfacial stresses, and dynamic contact line behavior.

C2weakest assumption

That active particle contributions can be reliably distinguished from and controlled independently of passive evaporation, Marangoni, and pinning effects in real droplet experiments.

C3one line summary

Active particles in drying droplets create self-driven flows and gradients that modify assembly patterns and contact line dynamics compared to passive evaporation-driven systems.
