Adhesion01:14

Adhesion

45.2K
Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow...

Mechanism of Filopodia Formation

3.3K
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...

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...

Summary

Spider capture silk adhesion depends on glue droplet shape. Optimal droplet spreading maximizes prey capture, while poor spreading reduces adhesion by altering crack propagation. This informs biomimetic adhesive design.

Area of Science:

  • Biomimetics
  • Materials Science
  • Arachnology

Background:

  • Orb web spiders utilize capture spiral silk with glue droplets for prey retention.
  • Capture silk adhesion is known to be humidity-dependent, with optimal performance varying by species.
  • Previous hypotheses focused on glue viscoelasticity for adhesion, linking it to humidity response.

Purpose of the Study:

  • To investigate the role of glue droplet shape in the adhesion of spider capture silk.
  • To determine how variations in droplet spreading affect adhesion mechanics.
  • To understand the relationship between droplet morphology, crack propagation, and failure regimes in capture silk.

Main Methods:

  • Analysis of glue droplet morphology during peeling events.
  • Investigation of how overspreading and underspreading impact adhesion.
  • Examination of changes in crack propagation and failure mechanisms related to droplet shape.

Main Results:

  • Glue droplet shape during peeling significantly influences capture silk adhesion.
  • Both overspreading and underspreading of glue droplets lead to reduced adhesion.
  • Adhesion reduction is attributed to altered crack propagation and failure regimes.

Conclusions:

  • Droplet shape is a critical factor, not just viscoelasticity, in spider silk adhesion.
  • Understanding these mechanics can inspire novel stimuli-responsive adhesive technologies.
  • Biomimetic adhesives can be designed by controlling droplet morphology for specific applications.
