    Microsphere-based biosensors have been attracting the attention of the photonics community due to their high sensitivity, selectivity and implementation. Microspheres, with their high quality-factor (Q-factor) morphology dependent resonances, are very sensitive to refractive index and size changes. The perturbation of the microsphere morphology dependent resonances can be used for the detection of... View full abstract»

    Surfactant-coated amorphous titania nanospheres have been synthesised using templating 'water-in-supercritical carbon dioxide' emulsion droplets; the process represents a clean and controlled method for the manufacture of high-purity nanoparticles. View full abstract»

    The effect of applying an external load to actin filaments moving in the in vitro motility assay is studied. Bead-tailed actin filaments were made by polymerising actin onto 2.8 μm diameter Dynabeads conjugated with gelsolin-G actin. These were introduced into a motility cell coated with 100 μg/ml rabbit fast skeletal myosin in the presence of ATP and 0.5% methylcellulose. The motility cell ... View full abstract»

    A novel polymer-coated adsorbent (subtractive adsorbent) has been manufactured and evaluated for the recovery of nanoparticle bioproducts. The core principle was to coat inert macroporous polymers (e.g. agarose) upon adsorbent beads of varied ligands. Here BSA nanoparticles, with an average nanoparticle diameter 95 nm, were fabricated and selected as feedstock for the demonstration of the principl... View full abstract»
