“…Baumgart et al [2007] demonstrated that the giant plasma membrane vesicles (GPMVs) induced on the plasma membranes of cultured mammalian cells can also be separated into micron-scale fluid phase domains, suggestive of a non-ideal, non-randomized distribution (19) of membrane components in living cells (19), further corroborating the existence of lipid rafts, and providing a classical tool to understand the formation and kinetics of lipid rafts. (24). These studies on the physical properties of lipid rafts have greatly promoted the development of the lipid raft theory.…”

Background and Objective: The distribution of components in the cell membrane is not uniform, but is organized into specific functional microdomains, known as "lipid rafts". These lipid rafts consist of cholesterol, sphingolipids, and various proteins. Studies have shown that lipid rafts contain multiple proteins that are closely related to signal transduction and immune response. Furthermore, lipid rafts are the sites where a variety of pathogens invade the cells, and are associated with the persistent infection of some pathogens, especially Helicobacter pylori (Hp). We are going to explore a new method to treat Hp by discussing the important role of lipid rafts in Hp persistent infection.Methods: Papers on lipid rafts were retrieved to analyze the evolution of the definition of lipid raft, research techniques, and studies on the correlation of lipid rafts with pathogens infecting host cells.

“…Despite continuous efforts using labelless detection techniques, random outbreaks of l o phases in time and space manner remain a hurdle to the elucidation of the physicochemical interactions between lipids and their kinetics during raft formation. Recently, fluorescent-free, non-disruptive, and real-time analytical devices for the monitoring of time-lapse kinetic dynamics of l o domain formations and the resultant membrane phase changes, together with the raft-participant ligand-receptor bindings, have been experimentally demonstrated 68 . As a compromise between the GUV and SLB systems, the periodically arranged nanohole array allows for an enhanced optical resonance signal, denoted as the localized SPR (LSPR) phenomenon, for the study of the binding kinetics of proteins with their binding partners, anchored in the lipid membrane 93 .…”

Lipid membranes and their applications in analytical biochip devices represent a great tool for the study of membrane dynamics and the related biological phenomena. Lipid-membrane-assisted surfacesensitive sensors have employed to provide biological information as they improve molecular survivability as well as rule out incorrect signals arising from unwanted nonspecific binding between target molecules with sensor surfaces. To enhance the accuracy of the signal as well as the sensitivity of biochip sensors, a variety of strategies have been employed. Here, we introduce various types of in vitro model membrane platforms/techniques and discuss current challenges in the lipid-membrane-assisted surface-sensitive analytical sensors application.

“…Notably, myelin is mainly composed of lipid (70-85% of dry mass), protein (15-30% of dry mass), and has water content of about 40% [132]. Ryu et al [133] reported the development of a novel and versatile membrane platform, which is continuous but spatially heterogeneous, to monitor the time-lapse dynamics of lipid-lipid interactions during the transient raft functional domain formation and sequential raft-associated receptor-ligand interactions.…”

Surface Plasmon Resonance (SPR) offers a powerful tool for label-free and non-invasive characterization of biomolecular interactions. To date, several experimental configurations, based on two fundamental physical phenomena, e.g., attenuated total reflection and diffraction, have been developed to measure the SPR signal generated due to the resonant interactions between incident light and plasma waves on the metal surface. These configurations are divided into three categories: grating-based, prism-based, and waveguide-based coupling. Among such techniques, one of the prism-based SPR coupling schemes, popularly known as Kretschmann configuration, is most widely used due to its high sensitivity, operational simplicity, lower cost, and real-time detection. This chapter explains the basic instrumentation and reviews the recent trends in the development of Kretschmann configuration-based SPR biosensors with its applications.
