English ivy (Hedera helix) is well known for its ability to climb onto and strongly adhere to a variety of solid substrates. It has been discovered that the ivy aerial rootlet secretes an adhesive composed of polysaccharide and spherical nanoparticles. This study aims to characterize the mechanical properties of the nanocomposite adhesive using atomic force microscopy (AFM). The adhesive was first imaged by AFM to visualize the nanocomposite. Mechanical properties were then determined at… 

Real-time observation of the secretion of a nanocomposite adhesive from English ivy (Hedera helix).

Nanoparticle biofabrication using English ivy (Hedera helix)

An enhanced system for the production of English ivy adventitious roots and their nanoparticles by modifying GA7 Magenta boxes and identifying the optimal concentration of IBA for adventitious root growth was developed, the first such platform for growing and harvesting organic nanoparticles from plants.

Nanoparticle biofabrication using English ivy

Background: English ivy (Hedera helix) is well known for its adhesive properties and climbing ability. Essential to its ability to adhere to vertical surfaces is the secretion of a nanocomposite

High-Strength Adhesive Exuded from the Adventitious Roots of English Ivy

This chapter focuses on describing the recent advance in the exploration of a high-strength bioadhesive derived from the adventitious roots of English ivy, which is a root climber that possesses strong capacity to cling vertical surfaces.

Isolation and chemical analysis of nanoparticles from English ivy (Hedera helix L.)

It is concluded that the ivy nanoparticles are proteinaceous, making them ideal for sunscreen and cosmetic fillers, and may be used as nanocarriers for drug delivery.

Nanospherical arabinogalactan proteins are a key component of the high-strength adhesive secreted by English ivy

The spheroidal nanoparticles observed in the mucilage exuded by the English ivy were identified to be predominantly composed of arabinogalactan proteins (AGPs), a superfamily of hydroxyproline-rich glycoproteins present in the extracellular spaces of plant cells and substantiated the proposed adhesion mechanisms underlying the ivy-derived adhesive.

Structure Characterization and Adhesive Ability of a Polysaccharide from Tendrils of Parthenocissus heterophylla

The analysis of force curves indicated that PT-A was a kind of elastic polysaccharide with a maximum adhesion force of 279.98 nN, which could be applied as a potential bio-adhesive.

Inspiration from the natural world: from bio-adhesives to bio-inspired adhesives

This paper reviews recent discoveries in animal and plant bio-adhesives, and details the mechanisms used in several representative biological systems, and extends the review to include the fundamental principles functioning in each form of adhesion at the micro- and nanoscales.

Recent Physical Interaction-based Bioadhesives

For centuries, research scientists and surgeons have been searching for the best way to close a wound from soft tissue to hard tissue. A number of wound closure techniques have been developed from

Branching morphology and biomechanics of ivy (Hedera helix) stem-branch attachments.

Coalescence of woody strands in H. helix ramifications results from accumulation of secondary xylem with age, influenced by mechanical stimuli causing specific loading situations during different growth habits, and fracture toughness of self-supporting H. Helix axes with merged stem-branch attachment regions are comparable to other self- supporting plant species, despite anatomical and ontogenetic differences.



Nanoparticles secreted from ivy rootlets for surface climbing.

Ivy secretes nanoparticles through adhering disks of the ivy aerial rootlets which allow the plant to affix to a surface, suggesting that the nanoparticles play a direct and important role for ivy surface "climbing".

Adhesion force studies of nanofibers and nanoparticles.

Numerical models demonstrated that local deformation of the fiber surface, including the flattening of surface asperities and the nanofiber wrapping around the particle during contact, may have a significant impact on the adhesion force.

This work provides the first direct experimental evidence for dry adhesion of gecko setae by van der Waals forces, and suggests a possible design principle underlying the repeated, convergent evolution of dry adhesive microstructures in gecko, anoles, skinks, and insects.

Nanoparticles to increase adhesive properties of biologically secreted materials for surface affixing.

It is discovered that marine mussels secrete large amounts of adhesive materials in the form of nanoparticles for surface adhesion, which indicates that nanoparticles are used by natural, biological systems to increase surfaceAdhesion.

Adhesion of the Boston ivy tendril

Electro microscopic examination of Boston ivy tendrils indicates that adhesive secretion occurs from the peripheral cells at the contact face of the discs, indicating that the adhesive is possibly a mucopolysaccharide.

Identification and functional characterization of a novel barnacle cement protein

The function of the protein was suggested to be coupling to foreign material surfaces during underwater attachment, and agreement between the molecular mass determined by MS and the molecular weight estimated from the cDNA indicated that the protein bears no post‐translational modifications.

Multiscale structure of the underwater adhesive of Phragmatopoma californica: a nanostructured latex with a steep microporosity gradient.

The structure of the adhesive joints was examined at the micro- and nanoscopic length scales using laser scanning confocal and atomic force microscopies and appeared to be an accretion of trillions of deformable nanospheres, reminiscent of a high-solids-content latex adhesive.
