Slippery surfaces provide a new way to solve the adhesion problem. This protocol describes how to fabricate slippery surfaces at high temperatures. The results demonstrate that the slippery surfaces showed anti-wetting for liquids and a remarkable anti-adhesion effect on soft tissues at high temperatures.

Dynamic adhesion of immune cells to the vessel wall is a prerequisite for gut homing. Here, we present a protocol for a functional in vitro assay for the impact analysis of anti-integrin antibodies, chemokines or other factors on the dynamic cell adhesion of human cells using addressin-coated capillaries.

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 glass...

Static adhesion assay is a powerful tool that can be used to model the interactions between T lymphocytes and other cell types. Interactions are generated by injecting labeled T cells into wells coated with adhesion molecules, while a plate reader is used to quantify the number of adherent cells following serial washes.

This flow adhesion assay provides a simple, high impact model of T cell-epithelial cell interactions. A syringe pump is used to generate shear stress, and confocal microscopy captures images for quantification. The goal of these studies is to effectively quantify T cell adhesion using flow conditions.
FAQs
It reduces several pathways that can make separation difficult. A low-surface-energy interface weakens chemical interaction between the contacting materials, while the interfacial film can also reduce mechanical interlocking and material transfer. These combined effects help surfaces separate with less force or damage, which is important when the contacting components include delicate patterns or structures.
A low-surface-energy interface primarily reduces the tendency of the two surfaces to interact strongly when they meet. A sacrificial boundary instead serves as an intervening film that limits direct contact and may be consumed or disrupted during separation. Both mechanisms reduce adhesion, but they do so through different interfacial roles and can support controlled release.
Material transfer can alter the surfaces involved in repeated contact and separation, potentially contributing to surface damage or inconsistent processing. By limiting transfer, an anti-adhesion layer helps preserve the intended interface and supports more reliable operation. In pattern-forming processes, this protection can also help maintain pattern fidelity rather than distorting features during separation.
During mold release, the layer is positioned at the mold or parting interface so the formed component can separate without strong bonding to the tool. In composite manufacturing, it can help manage separation between processing surfaces and the composite structure. These uses connect interfacial control with easier release, reduced damage, and more consistent processing.
The layer is applied as an interfacial boundary between the pattern-forming surface and the material being processed. During separation, it reduces bonding and material transfer that could disturb small features. This role is especially relevant to microfabrication and nanoimprint lithography, where preserving pattern fidelity during release directly supports the quality and repeatability of the patterned structure.
They provide a deliberately engineered interface that limits the strength and consequences of contact between bonded components. By reducing chemical interaction, mechanical interlocking, and transfer across the boundary, the layer makes separation more controlled. In engineering systems, that can protect surfaces, reduce damage during disassembly or release, and improve overall process reliability.
