Adhesion

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...

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University The glovebox provides a straightforward means to handle air- and moisture-sensitive solids and liquids. The glovebox is what it sounds like: a box with gloves attached to one or more sides, which allows the user to perform manipulations within the glovebox under an inert atmosphere. For manipulations under inert atmospheres, chemists can choose between Schlenk or high-vacuum techniques and a glovebox. Schlenk and...

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.

We describe an electrochemical sensor assay method for rapid bacterial detection and identification. The assay involves a sensor array functionalized with DNA oligonucleotide capture probes for ribosomal RNA (rRNA) species-specific sequences. Sandwich hybridization of target rRNA with the capture probe and a horseradish peroxidase-linked DNA oligonucleotide detector probe produces a measurable amperometric current.

This article will demonstrate how to monitor glutamine dynamics in live cells using FRET. Genetically encoded sensors allow real-time monitoring of biological molecules at a subcellular resolution. Experimental design, technical details of the experimental settings, and considerations for post-experimental analyses will be discussed for genetically encoded glutamine sensors.
FAQs
Their flexible sensing materials respond to physical or chemical changes at the biological interface. Strain, pressure, temperature, or chemical composition produces a corresponding electrical output, which can then be recorded and analyzed. This transduction process allows one device platform to capture different health-related signals, depending on the sensing material and the variable being monitored.
Conformal contact helps the device remain closely aligned with skin or another biological surface while the wearer moves. The adhesive interface supports stable sensing contact without requiring bulky equipment, making measurements more suitable for continuous monitoring. This design also contributes to comfort and portability, which are important when monitoring patients over extended periods.
Adhesive sensors emphasize lightweight, flexible attachment directly to the body rather than relying on larger monitoring equipment. Their low-profile format can support noninvasive and continuous measurements while allowing greater portability. In clinical use, this distinction may make physiological data collection more compatible with everyday activity, remote management, and settings where conventional equipment is less practical.
A typical workflow begins by attaching the sensor to skin or another relevant biological surface so that its interface maintains contact. The device detects a selected physiological or biochemical change, converts that change into an electrical output, and sends the resulting data for recording and analysis. The analyzed signals can then support monitoring or clinical assessment.
Clinical applications include tracking movement, cardiac activity, respiration, wound conditions, and other health indicators. The appropriate sensing function depends on whether the target involves strain, pressure, temperature, or chemical composition. By collecting these signals directly from the body, the devices can contribute to noninvasive monitoring and provide information for point-of-care diagnostics.
Their comfort, portability, and potential for long-term wear make adhesive sensors useful when clinicians need information beyond a brief measurement. Continuous data can support personalized care by revealing health-related changes over time, while the compact format suits remote health management. The same capabilities may also help extend monitoring outside conventional clinical environments and support point-of-care assessment.
