Photonic crystal enhanced microscopy for imaging of live cell adhesion
… time-resolved images of the evolution of cell attachment and morphology during chemotaxis and drug-induced apoptosis. It enabled the monitoring of cell behavior with spatial resolution sufficient for observing intracellular attachment strength gradients. PCEM was also used to image fluorescence …

Cell biology of settlement and adhesion processes of biofouling algae
… attached more strongly. Increased NO reduced attachment strength and it is thought that NO may play a signalling and/or regulatory role in diatom adhesion.

Paravalvular sealing pf percutaneous heart valves
… attach the scaffolds to pre-coated TAVR stents. Attachment strength was modelled by finite element analysis (FEA) of stents in the crimped and expanded conditions and empirically determined by physical pull-off tests. PVR was evaluated for four different skirt designs (1× single layer “FLAT” and …

Label free imaging of cell attachment by photonic crystal enhanced microscopy
… the sensor surface, allowing detection of cell attachments without bias due to diffraction or absorption by cellular organelles. This work demonstrates the new capabilities this technique offers. Human hepatic and pancreatic cancer cells were imaged at different time points after settling in …

Distribution and Characteristics of Biomass in an Upflow Biological Aerated Filter
… divided in three fractions depending on their attachment strength to the media: detached, easily detachable and strongly attached. VSS measurement showed that the detached and easily detachable fractions accounted for 25 to 40% of the biomass in the bed and are present even after backwash. …

New approaches to understanding the interactions between Plasmodium falciparum merozoites and human erythrocytes during invasion
… interactions and multiple steps. It begins with attachment of the parasite to the erythrocyte, followed by reorientation to position the parasite to invade, then strong membrane wrapping occurs, and finally, a tight junction is formed, which passes around the merozoite, forming the …

The effects of biotic and abiotic factors on byssogenesis, growth and movement patterns of the blue mussel, Mytilus edulis
… in increased byssal thread production and attachment strength in large mussels, whereas movement ability in small mussels is reduced in the presence of epibionts. Upon exposure to crab effluent, mussels produced more byssal threads while mussels exposed to effluent of injured conspecifics …

Assembly and autoinhibitory mechanisms of the budding yeast kinetochore KMN complex
… mediate chromosome segregation by forming robust attachments to microtubules under applied force, and act to ensure the accuracy of chromosome segregation by scaffolding signalling pathways that regulate cell cycle progression and kinetochore-microtubule (KT-MT) attachment strength. An inner …

Programmable adhesion in dry and wet environments through geometric design
… to complex surface conditions for effective attachment. The curvature of the stalk enhances attachment by increasing conformal contact on large-scale curvatures and improving contact stress around the stalk's perimeter, which allows it to better adapt to small-scale roughness. This enables …

3D Printing on Textile Fabrics Based on Material Extrusion
… in the development of a method for assessing the attachment strength in the interface between printed object and surface of textile fabrics and the understanding of the processes to achieve strong attachment of 3D printed patterns on the fabrics. A wide range of thermoplastic filaments are …

Documenting the association between a non-geniculate coralline red alga and its molluscan host
To further investigate the strength of the association and the relative advantages of the association to both organisms, several manipulation experiments were set up. A cage experiment set up in the shallow subtidal zone showed that the coralline survived equally well without the winkle and did …
