Microtubule Instability

Microtubule Instability

Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Mechanism of Lamellipodia Formation

Mechanism of Lamellipodia Formation

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...

Mechanism of Filopodia Formation

Mechanism of Filopodia Formation

Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

The Colloidal State

The Colloidal State

The formation of a colloidal system is exemplified by an aqueous solution containing Cl− ions is introduced to another containing Ag+ ions, resulting in the precipitation of solid AgCl as extremely tiny crystals. Instead of settling out as a filterable precipitate, these crystals remain suspended in the liquid, showcasing a colloidal system.A colloidal system involves colloidal particles within the approximate range of 1 to 1000 nm in at least one dimension, dispersed in a medium called...

Area of Science:

Materials Science
Soft Matter Physics
Surface Science

Background:

Thin polymer films spontaneously form complex structures on their free surfaces.
Understanding these self-organization phenomena is crucial for advanced material design.

Purpose of the Study:

To classify and review the instabilities of thin polymer films.
To analyze the influence of material properties and external fields on structure formation.
To explore strategies for controlling and ordering these self-organized patterns.

Main Methods:

Classification of instabilities into three categories based on underlying physical mechanisms.
Review of factors influencing characteristic length scales, morphology, and evolution pathways.
Discussion of bottom-up and top-down approaches for pattern alignment.

Main Results:

Category 1: Instability in ultra-thin films driven by van der Waals forces and capillary waves.
Category 2: Instability due to surface interactions between elastic films and rigid surfaces.
Category 3: Field-induced instability (electric or thermal) in viscous and elastic films.

Conclusions:

Polymer film instability is governed by distinct mechanisms, influenced by film properties and external stimuli.
Strategies exist to control self-organized structures, merging bottom-up and top-down fabrication.
Further research can refine patterning techniques and explore novel applications.
