  • METHODS AND SYSTEMS FOR OPTICAL CHARACTERISATION
    Publication number: 20120293797
    Abstract: An optical device is described for irradiating at least one object in a medium. The optical device may be a microfluidics device, and comprises at least one integrated planar waveguide that enables providing sheet irradiation of objects in the medium. A characterization system including such an optical device and a corresponding method of characterizing an object or a fluid are described.

  • COATING FOR MICROCARRIERS
    Publication number: 20100081215
    Abstract: The present invention relates to carriers, which are coated by at least one layer of polyelectrolytes and one layer of magnetic material. These carriers can be manipulated in a magnetic field. The application of the coating of the present invention on microcarriers comprising a fluorescent core results in a carrier with a homogeneous luminescence. Additionally, where the core is provided with a code, this allows improved reading thereof.

  • Therapeutic compositions for the treatment of a respiratory tract disease
    Patent number: 7432308
    Abstract: The equilibrium between G actin and F actin is shifted towards the F actin confirmation with compounds such as the ionic form of magnesium or potassium. The higher amount of F actin decreases the inhibition of nucleases such as DNAse I by monomeric G actin. The increased performance of the nuclease results in better treatment of patients suffering from cystic fibrosis or other diseases with viscous mucus.

  • Encoding of microcarriers
    Publication number: 20060097056
    Abstract: Encoded microcarriers, and more specifically microcarriers having codes written on them. Methods for writing the codes on the microcarriers, methods of reading the codes, and methods of using the encoded microcarriers. A preferred method of encoding the microcarriers involves exposing microcarriers containing a bleachable substance to a high spatial resolution light source to bleach the codes on the microcarriers. The encoded microcarriers may be used, for example, as support materials in chemical and biological assays and syntheses.

  • Pulsed bio-agent delivery systems based on degradable polymer solutions or hydrogels
    Publication number: 20040258753
    Abstract: A degradable oligomer or polymer aqueous solution or a degradable polymer hydrogel, wherein degradation occurs by cleavage of the oligomer or polymer backbone and/or, in the case of a hydrogel, by cleavage of cross-linking bonds within the hydrogel, is useful as a component of a time-controlled explosion bio-agent release system or a pulsed bio-agent delivery system comprising at least one biologically active agent and an outer semi-permeable lipid or polymer membrane, wherein bio-agent release or delivery begins after a lag time.
