“…28,36 To investigate the potential origin of the observed anomalous behavior, we modified the membrane–substrate interaction and the degree of potential interleaflet coupling while keeping modifications to the assay to a minimum. First, we repeated our GM1 tracking experiments using chemically inert mica as a substrate.…”

The biological functions of the cell membrane are influenced by the mobility of its constituents, which are thought to be strongly affected by nanoscale structure and organization. Interactions with the actin cytoskeleton have been proposed as a potential mechanism with the control of mobility imparted through transmembrane “pickets” or GPI-anchored lipid nanodomains. This hypothesis is based on observations of molecular mobility using various methods, although many of these lack the spatiotemporal resolution required to fully capture all the details of the interaction dynamics. In addition, the validity of certain experimental approaches, particularly single-particle tracking, has been questioned due to a number of potential experimental artifacts. Here, we use interferometric scattering microscopy to track molecules labeled with 20–40 nm scattering gold beads with simultaneous <2 nm spatial and 20 μs temporal precision to investigate the existence and mechanistic origin of anomalous diffusion in bilayer membranes. We use supported lipid bilayers as a model system and demonstrate that the label does not influence time-dependent diffusion in the small particle limit (≤40 nm). By tracking the motion of the ganglioside lipid GM1 bound to the cholera toxin B subunit for different substrates and lipid tail properties, we show that molecular pinning and interleaflet coupling between lipid tail domains on a nanoscopic scale suffice to induce transient immobilization and thereby anomalous subdiffusion on the millisecond time scale.

“…In other words, the AFM lateral force measurement is a powerful method to detect the difference of surface properties. The future complementary experiments including roughness measurements with super-sharp AFM tips and surface analyses with techniques such as FTIR, XPS, and SE [2][3][4][5] will provide further insights on the relation between the cleaning approach and the wafers tribology.…”

“…Since the presence of organic contaminants and mechanical impurities reduces the quality of silicon oxides, such as the uniformity and reproducibility of functionalized surfaces, the cleaning of silica surfaces is of crucial importance [1]. The quality of cleaned surfaces has been characterized using various methods, such as the measuring methods using the contact angle, the atomic force microscope (AFM), the Fourier transform infrared reflectance (FTIR), the X-ray photoelectron spectroscopy (XPS), and the spectroscopic ellipsometry (SE) [2][3][4][5].…”

“…24,25 This has the effect of making the surface of glass slightly negatively charged and any positively charged particles in vicinity would be attracted to the glass surface forming layers such as those, e.g. A and B, thereby exaggerating the aforementioned problem of particles sticking to the glass surface.…”

Multilayer transparent electrode consisting of silver alloy layer and metal oxide layers for organic luminescent electronic display device An optical shutter based on charged particles is presented. The output light intensity of the proposed device has an intrinsic dependence on the interparticle spacing between charged particles, which can be controlled by varying voltages applied to the control electrodes. The interparticle spacing between charged particles can be varied continuously and this opens up the possibility of particle based displays with continuous grayscale.
