Mechanism of Lamellipodia Formation01:31

Mechanism of Lamellipodia Formation

3.9K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

Area of Science:

  • Physics
  • Materials Science
  • Fluid Dynamics

Background:

  • Droplet evaporation leads to particle deposition, often forming coffee ring stains.
  • Understanding particle rearrangement dynamics is crucial for controlling deposition patterns.

Purpose of the Study:

  • To investigate particle rearrangement in the final stages of droplet evaporation.
  • To elucidate the formation mechanism of network patterns within coffee ring stains.

Main Methods:

  • Utilized differential interference contrast microscopy for real-time observation.
  • Employed a tailored substrate with a circular hydrophilic domain to create a thin liquid film with monolayer particles.
  • Analyzed bottom-view images to track dry patch evolution.

Main Results:

  • The evolution of dry patches during liquid film dewetting occurs in three stages: rupture initiation, expansion, and residual liquid drying.
  • Multiple dry patches form and repeat these stages, leading to the characteristic network patterns within the stain.
  • The suction effect significantly promotes liquid film rupture and dry patch formation.

Conclusions:

  • Particle assembly during droplet evaporation is governed by liquid film dewetting processes.
  • Surface tension of the liquid film is the dominant factor determining the final particle deposition patterns.
  • The study reveals a fundamental mechanism for pattern formation in evaporating colloidal systems.
