Magnetomicrometry : tissue length tracking via implanted magnetic beads
… that tracks visually-obscured magnetic beads implanted within biological tissue to monitor in-vivo tissue length and speed within freely moving animals and humans. There are many methods to track visually-obscured objects, but magnetic-target tracking has the advantages of being …

Elution of Metronidazole and Gentamicin from Polymethylmethacrylate Beads
Ten polymethylmethacrylate (PMMA) beads containing metronidazole (3 concentrations); gentamicin sulfate; or metronidazole and gentamicin sulfate were immersed in 5 ml of phosphate buffered saline in triplicate. Eluent was replaced at specified time intervals for 1 day (1, 3, 6, 12 and 24 hours), …

Quantum dot encoded magnetic beads for multiplexed fluorescence biosensing
In recent years, the use of encoded beads has received considerable attention due to their potential for measuring multiple analytes in solution.(1-4) This can be achieved without the need for knowledge of their spatial position, as in the case of microarray technology. Encoded bead technology also …

Story beads : a wearable for distributed and mobile storytelling
… repurposing of images and image sequences. StoyBeads are wearable computers developed as a tool for constructing image-based stories by allowing users to sequence and trade story pieces of image and text. StoyBeads are modular, wearable computer necklaces made of tiny computer "beads" capable of …

Polymer coated superparamagnetic beads walking on polymer coated surface
… walkers that are created using superparamagnetic beads placed in a rotating external magnetic field. Dipoles align in the beads so they assemble into rotors. These rotors follow the rotating magnetic field and are able to translate across a surface. This work looks at the effect of coating the …

Removal of nitrate from contaminated groundwater by floating alginate beads
… in multiple batches of lab synthesized alginate beads, which have the III characteristics of initially sinking in water but later floating on the surface. A methodology was introduced to produce NP-impregnated alginate beads, and later impacts of alginate presence was assessed on the efficiency …

Modelling the movement of superparamagnetic beads engulfed in endothelial cells
… scaffold is facilitated with superparamagnetic beads introduced to the cells by phagocytosis. It is shown that the dominant motion of the affected cells is determined by the viscous drag of the medium and the amount of coupling with an externally imposed magnetic field. An efficient numerical …

An investigation of occlusions within polymer beads produced by suspension polymerisation
… of some of the continuous phase within polymer beads produced by suspension polymerisation is well-known, although little understood by the polymer industry. Occluded aqueous phase of levels approaching 30'/o (w/w) can give rise to major difficulties in handling the finished product, …

Towards ultrahigh-throughput phenotypic screening using microfluidic droplets and functionalised polyacrylamide beads
… and microfluidic-compatible polyacrylamide microbeads. We envision this as an ultrahigh-throughput-compatible, robust, abiotic tool for maintaining the genotype-effector (“phenotype”) linkage over several experimental steps (e.g. PCR, in vitro expression, and the assay itself), as well as a …

Magnetic domain walls for on-chip transport and detection of superparamagnetic beads
… superparamagnetic (SPM) microbeads are of great interest in biomedical research and diagnostic device engineering for tagging, manipulating, and detecting chemical and biological species in a fluid environment. At the same time, lab-onchip technologies have grown popular due to …

Evaluation of the in vitro elution characteristics of carboplatin-impregnated calcium sulfate beads
… calcium sulfate hemihydrate (CSH) beads in vitro. Sample: Sixty carboplatin-impregnated CSH beads and 9 CSH beads without added carboplatin (controls) Procedures: Carboplatin-impregnated CSH beads (each containing 4.6 mg carboplatin [2.4 mg platinum]) were placed into separate 10 mL …

Cyclic loading of fibronectin coated beads induces differentiation in mouse embryonic stem cells
… through fibronectin (FN) coated magnetic microbeads. The ligand coated magnetic beads were allowed to bind to undifferentiated mES cells plated on 0.6 kPa polyacrylamide gels prior to loading. The cells used were stably transfected with green fluorescent protein (GFP) bound to oct3/4, an …

Production and Use of Alginate Beads Containing Yeast in a Novel Fluidised Bed Bioreactor
The Production and Use of Alginate Beads Containing Yeast in a Novel Fluidised Bed Bioreactor It was found experimentally that sodium alginate solutions between 1 and 6% concentration formed drops with diameters between 3 and 5 mm at a single fluid nozzle. Drop diameter was largely determined by …

Preparation and characterization of cross-linked chitosan beads for phosphate adsorption in aqueous solution
Chitosan beads were cross-linked with glutaraldehyde (GA) and epichlorohydrin (EP), respectively, at variable composition. The cross-linked chitosan beads were further modified and doped using calcium chloride. Several techniques were used to characterize the structural and chemical properties of …

Leaching of metals and metalloids from highway marking glass beads and the potential environmental impact
Glass beads are embedded in pavement markings to obtain retroreflectivity which plays a crucial role in the lighting-up effect needed for safe driving. Elevated metal and metalloid concentrations of As, Sb, and Pb have recently been observed in imported glass beads. The main objective of this …
