Characterizing the structure of lipodisq nanoparticles for membrane protein spectroscopic studies.

Biochim. Biophys. Acta 1848(1 Pt B) , 329-33, (2015)

Membrane protein spectroscopic studies are challenging due to the difficulty introduced in preparing homogenous and functional hydrophobic proteins incorporated into a lipid bilayer system. Traditional membrane mimics such as micelles or liposomes have proved...

Effect of asymmetrical flow field-flow fractionation channel geometry on separation efficiency

J. Chromatogr. A. 1217(24) , 3876-80, (2010)

The separation efficiencies of three different asymmetrical flow field-flow fractionation (AF4) channel designs were evaluated using polystyrene latex standards. Channel breadth was held constant for one channel (rectangular profile), and was reduced either l...

Transformation of unipolar single-walled carbon nanotube field effect transistors to ambipolar induced by polystyrene nanosphere assembly.

ACS Nano 2(12) , 2526-30, (2008)

We have fabricated single-walled carbon nanotube (SWNT) field effect transistors (FETs) with molybdenum source and drain contacts. Normally, these devices operate only as p-channel transistors, however, after polystyrene latex nanospheres were attached to the...

A new measure of molecular attractions between nanoparticles near kT adhesion energy.

Nanotechnology 20(27) , 275701, (2009)

The weak molecular attractions of nanoparticles are important because they drive self-assembly mechanisms, allow processing in dispersions e.g. of pigments, catalysts or device structures, influence disease through the attraction of viruses to cells and also ...

Study of colloidal particle Brownian aggregation by low-coherence fiber optic dynamic light scattering.

J. Colloid. Interface Sci. 376(1) , 322-6, (2012)

The aggregation kinetics of particles in dense polystyrene latex suspensions is studied by low-coherence fiber optic dynamic light scattering. Low-coherence fiber optic dynamic light scattering is used to measure the hydrodynamic radius of the aggregates. The...

Isotropic photo-decomposition of spherical organic polymers on rutile TiO₂(110) surfaces.

Nanotechnology 22(15) , 155705, (2011)

We observed the photo-decomposition process of polystyrene latex (PSL) spheres on a rutile TiO₂(110) single crystal surface by using atomic force microscopy. During the decomposition process, both the height and width of the PSL spheres linearly decreased wit...

Phagostimulatory effect of uptake of PLGA microspheres loaded with rifampicin on alveolar macrophages.

Colloids Surf. B Biointerfaces 87(2) , 293-8, (2011)

Our previous results on the phagocytic activity of alveolar macrophages (Mϕs) toward poly(lactic-co-glycolic) acid microspheres (PLGA MS) loaded with the anti-tuberculosis agent rifampicin (R-PLGA MS) suggest that the phagocytosis of R-PLGA MS enhances the ph...

Preparation and evaluation of differently sulfonated styrene-divinylbenzene cross-linked copolymer cationic exchange resins as novel carriers for drug delivery.

AAPS PharmSciTech 10(2) , 641-8, (2009)

The differently sulfonated styrene-divinylbenzene cross-linked copolymer cationic exchange resins were prepared by oil-in-water polymerization and varied degrees of sulfonation. Several characteristics of the obtained resins were evaluated, i.e., Fourier tran...

Synthesis of anionic sulfate functionalized polystyrene latex and protein adsorption for application as a biosensor.

J. Nanosci. Nanotechnol. 9(12) , 7171-6, (2009)

Bare and surface modified polystyrene nanoparticles with an anionic sulfate end group were synthesized by emulsion polymerization for adsorption of a protein (immunoglobulin G, IgG) by passive adsorption and electrostatic attraction for application as a biose...

A method for articulating and displaying the human spine.

J. Forensic Sci. 54(6) , 1229-30, (2009)

An inexpensive and effective method for articulating a dry human spine is described. By constructing a Styrofoam spine tray, analysts can now accurately position and align each vertebra in correct anatomical order, allow for gaps because of missing vertebrae,...
