Monodispersed Magnetic Polystyrene Beads with Excellent Colloidal Stability and Strong Magnetic Response

Macromolecular Rapid Communications, 2010
Monodispersed polystyrene beads incorporated with FeO nanoparticles are prepared via dispersion polymerization. The resultant magnetic beads present well-defined composite structures, excellent colloidal stability, and strong magnetic response.

Biocidal polystyrene beads. IV. Functionalized methylated polystyrene

Journal of Applied Polymer Science, 2004
AbstractCrosslinked chloromethylated polystyrene beads were reacted with hydantoin and imidazolidinone derivatives to produce functionalized beads which could be rendered biocidal upon reaction with free chlorine or bromine. The biocidal efficacies of the N‐chlorinated, and in one case, the N‐brominated polymeric beads against Staphylococcus aureus and

SDS removal from protein by polystyrene beads

Analytical Biochemistry, 1978
Abstract The applications of sodium dodecyl sulfate (SDS) to molecular weight determination (1,2) and for the separation of protein subunits (3) have been of immense value in biochemical studies [see Waehneldt (4) for a general review]. The tight stoichiometric binding of SDS to polypeptide chains has proven to be a nuisance if one desires to recover

Influence of temperature and charge effects on thermophoresis of polystyrene beads⋆

The European Physical Journal E, 2016
We study the thermodiffusion behavior of spherical polystyrene beads with a diameter of 25 nm by infrared thermal diffusion Forced Rayleigh Scattering (IR-TDFRS). Similar beads were used to investigate the radial dependence of the Soret coefficient by different authors. While Duhr and Braun (Proc. Natl. Acad. Sci. U.S.A.

Complement inhibition reduces material‐induced leukocyte activation with PEG modified polystyrene beads (Tentagel™) but not polystyrene beads

Journal of Biomedical Materials Research Part A, 2005
AbstractWith isolated leukocytes, inhibiting complement reduced material‐induced leukocyte activation (CD11b) with polyethylene glycol modified polystyrene beads (PS‐PEG), but not with polystyrene beads (PS). The PS‐PEG beads (TentaGel™) were complement activating as measured by SC5b‐9 levels consistent with the sensitivity of these beads to leukocyte ...

Evaporation Kinematics of Polystyrene Bead Suspensions

Langmuir, 1997
A study of the evaporation of polystyrene sphere−H2O suspensions placed on nonwetting surfaces was conducted using a video camera and computer-imaging interface. The height, diameter, contact angle, and mass were measured as functions of time for a range of sessile drop sizes, polystyrene sphere diameters, and initial suspension concentrations.

Plasmachemical Functionalization of Porous Polystyrene Beads

Chemistry of Materials, 2001
XPS, ATR-FTIR, 19 F MAS solid-state NMR, and imaging TOF-SIMS have been used to compare the depth and extent of chemical modification achieved during nonisothermal CF 4 plasma fluorination of nonporous, mesoporous, and microporous polystyrene spheres.

Isolation of Polystyrene Bead-Induced Phagosomes for Western Blotting

2023
The engulfment of "self" and "non-self" particles by immune and non-immune cells is crucial for maintaining homeostasis and combatting infection. Engulfed particles are contained within vesicles termed phagosomes that undergo dynamic fusion and fission events, which ultimately results in the formation of phagolysosomes that degrade the internalized ...

Bead‐to‐fiber transition in electrospun polystyrene

Journal of Applied Polymer Science, 2007
AbstractThe morphological transition, namely bead‐to‐fiber transition, of electrospun polymer was examined for polystyrene, with its molecular weight ranging from 19,300 to 1,877,000 g/mol. Tetrahydrofuran and N,N‐dimethylformamide were used as solvents to examine the effects of solvent properties on the morphological variations.
