Observations on the behavior of a frog leucocyte in vivo have led to the conclusion that an adhesive force of at least 10(-5) dynes may be offered by one pseudopod. This adhesive force, of one pseudopod, is of the order of magnitude sufficient to cause leucocyte arrest previous to emigration through the capillary wall.

Cell adhesion and spreading on fluid membranes through microtubules-dependent mechanotransduction.

Integrin clusters facilitate mechanical force transmission (mechanotransduction) and regulate biochemical signaling during cell adhesion. However, most studies have focused on rigid substrates. On fluid substrates like supported lipid bilayers (SLBs), integrin ligands are mobile, and adhesive complexes are traditionally thought unable to anchor for cell spreading.

Type 4 pili (T4P) are multifunctional filaments involved in adhesion, surface motility, biofilm formation, and horizontal gene transfer. These extracellular polymers are surface-exposed and, therefore, act as antigens. The human pathogen Neisseria gonorrhoeae uses pilin antigenic variation to escape immune surveillance, yet it is unclear how antigenic variation impacts most other functions of T4P.

This study aimed to compare the bonding efficacy three bioactive self-adhesive restorative systems to dentin. A total of 80 permanent human molars were utilized in this study. The occlusal enamel was removed to exposed mid-coronal dentin; 40 molars were used for microshear bond strength testing, while the remaining molars were used for micromorphological analysis of restoration/dentin interface.

Direct force measurements by atomic force microscopy (AFM) have become an indispensable analytical tool in the last decades. Force measurements have been widely used for adhesion measurements, often in combination with the colloidal probe technique. For the latter technique, a colloidal particle is attached to the end of an AFM cantilever, proving great flexibility in terms of colloid/surface interaction to be studied.
