Abstract
We report a novel and versatile approach for fabricating ordered nanoring arrays of metals, metal oxides, and other inorganic materials with diameter of sub-50 nm by loading the salt precursors in P4VP cores of PS-b-P4VP thin film and exposing these to methanol vapor which results in the P4VP blocks...

Abstract
A promising one-step homogeneous fluoroimmunoassay based on nanoscale-graphene sheets as powerful fluorescence acceptors and CdTe quantum dots as vigorous donors was designed to detect trace biomarker protein with distance-independent quenching efficiency, which significantly broke the distance limi...

Abstract
I (COL1) and fibronectin (FN) on cell adhesion, cell elasticity and cytoskeletal organization of prostate cancer cells. Two cell lines, bone marrow- (PC3) and lymph node-derived (LNCaP) were cultivated on COL1 and FN (control protein). By using a quantitative adhesion assay and time-lapse analysis,...

Abstract
Porosomes are the universal secretory machinery of the cell plasma membrane, where membrane-bound secretory vesicles transiently dock and fuse to expel intravesicular contents to the environment during cell secretion. In neurons, 12- to 17-nm cup-shaped lipoprotein structures possessing a central pl...

Abstract
We have presented a unique low cost arsenic removal technique using ferric hydroxide microcapsule-loaded alginate beads (FHMCA) as an adsorbent in a continuous packed column. The microencapsulated particles of ferric hydroxide were produced in a spray dryer and subsequently coated with calcium algin...

Abstract
Crystallization of L-cystine is a critical step in the pathogenesis of cystine kidney stones. Treatments for this disease are somewhat effective but often lead to adverse side effects. Real-time in situ atomic force microscopy (AFM) reveals that L-cystine dimethylester (L-CDME) and L-cystine methyle...

Abstract
The controlled reversal of supramolecular helical chirality in protein fibrils is reported for the first time. Normal or reversed insulin fibrils were grown by precise adjustment of pH. AFM images show two polymorphs corresponding to opposite senses of helical twist of the supramolecular structure w...

Abstract
The interaction between photosensitizer anticancer drug hematoporphyrin monomethyl ether (HMME) and ctDNA has been studied based on the decreased resonance light scattering (RLS) phenomenon. The RLS, UV-vis and fluorescence spectra characteristics of the HMME-ctDNA system were investigated. Besides,...

Abstract
We used specific AHNAK1 and AHNAK2 antibodies to analyzed the detailed localization of both proteins in mouse skeletal muscle. Co-localization of AHNAK1 and AHNAK2 with vinculin clearly demonstrates that both proteins are components of the costameric network. In contrast, no AHNAK expression was det...

Abstract
The applicability of CMCht/PAMAM dendrimer nanoparticles for CNS applications was investigated. AFM and TEM observations revealed that the nanoparticles possessed a nanosphere-like shape with a size from 22.0 to 30.7 nm. The nanoparticles could be bound to fluorescent-probe FITC fo...

Abstract
We were able to fine-tune the scaffold's persistence length and stiffness as perceived by cells. This was used to direct the outcome of the cell's cytoskeletal arrangement and overall shape, the status of its signal transduction protein p-FAK, and the localization of its intracellular transcription...

Abstract
We show experimentally the strength of the contribution of the seta surface architecture to superhydrophobicity by maintaining identical surface chemistry (thin and thick coating of the setae with polydimethylsiloxane). Atomic force microscopy-based force and adhesion measurements of single uncoated...

Abstract
Atomic force microscopy (AFM) can be used to visualize the three major cytoskeletal components that contribute to the mechanical properties of the cell. These are actin microfilaments, intermediate filaments, and microtubules. In this protocol, rat embryonic fibroblasts expressing actin tagged with...

Abstract
This protocol describes the preparation and use of spherical indenters for micrometer-scale imaging and mechanical testing with atomic force microscopy (AFM). A spherical indenter is prepared by gluing a hard borosilicate sphere to a tipless cantilever. For this purpose, a stereomicroscope with a mi...

Abstract
Atomic force microscopy (AFM) offers researchers a unique opportunity to visualize, manipulate, and quantitatively assess structural and mechanical aspects of native biological samples with nanometer resolution. An unparalleled advantage of AFM over other high-resolution microscopes is that biologic...

Abstract
Cartilage is a complex avascular tissue composed of cells ("chondrocytes") embedded in an extracellular matrix (ECM) consisting of 70%-80% water. The primary components of the ECM are negatively charged aggrecans and collagen II fibrils, which possess a characteristic, ordered three-dimensional stru...

Abstract
Collagen II is a fibrous protein that assembles from basic tropocollagen subunits to form extracellular supramolecular fiber networks within cartilage tissue. Tropocollagen subunits of ~300 nm in length self-assemble first into pentameric uniform microfibrils, which fuse into bigger collagen fibrils...

Abstract
We investigated the effect of various in vitro-aged Abeta(1-42) oligomer solutions on the perforant pathway-evoked field potentials in the ventral hippocampal dentate gyrus in vivo. Firstly, Abeta oligomer solutions (1 microl, 200 microM) which had been aggregated in vitro for 0, 24 or 72h were inje...

Optics Express (18)20 2010
Abstract
The paper deals with quantitative phase imaging of two-height-level surface reliefs. The imaging is considered to be a linear system and, consequently, the Fourier transform of the image is the product of the Fourier transform of a 2D function characterizing the surface and a specific 2D coherent tr...

Abstract
We evaluate the performance of AFM imaging specifically for quantifying supercoiled and relaxed plasmid DNA fractions within a mixture, and compare the results with the bulk material analysis method, gel electrophoresis. The advantages and shortcomings of both methods are discussed in detail. Gel el...
