Pinching-off of Coated Vesicles

Pinching-off of Coated Vesicles

Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...

Contact Angle

Contact Angle

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Background:

Capillary action between solid surfaces is vital for micro-object manipulation.
Understanding capillary bridges and forces is essential for designing micro-manipulation systems.

Purpose of the Study:

To investigate axisymmetric capillary bridges and forces between a spherical concave gripper and a spherical particle.
To analyze capillary bridge rupture characteristics and the influence of various parameters on capillary force.

Main Methods:

A numerical shooting method with double iterative loops was used to determine capillary bridge profiles and forces under constant volume conditions.
Capillary bridge rupture was characterized by parameters including neck radius, pressure difference, and half-filling angle.

Main Results:

The study discusses the effects of contact angle, radius ratio, and liquid bridge volume on dimensionless capillary force.
A significant influence of the radius ratio on dimensionless capillary force was observed for small dimensionless liquid bridge volumes (0.01, 0.05, 0.1) when the ratio is less than 10.

Conclusions:

The numerical approach provides an effective method for analyzing capillary forces in micro-object manipulation.
The findings offer valuable insights into the mechanics of capillary interactions for micro-scale applications.
