  • Patent number: 11712484
    Abstract: A method for generating vapour bubbles in an object comprises introducing a composition into the object, the composition comprising carbon-based nano- or microparticles that can couple with a photon wave of electromagnetic radiation. The method also comprises irradiating said object using electromagnetic radiation. The irradiation thereby is adapted for using a set of carbon-based nano- or microparticles for subsequently forming first vapour bubbles and at least second vapour bubbles using the same carbon-based nano- or microparticles.

  • Publication number: 20180200368
    Abstract: A method for altering and/or disrupting a microbiological film is described. The method comprises introducing a composition into a microbiological film, the composition comprising nano- or microparticles having an electron density that can couple with a photon wave of electromagnetic radiation. The method also comprises irradiating said microbiological film by said electromagnetic radiation such as to form a vapour bubbles using said nano- or microparticles in said microbiological biofilm, thereby generating a mechanical force for locally altering and/or disrupting said microbiological film when said vapour bubbles expand and/or collapse.

  • Patent number: 8967483
    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.

  • 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.

  • 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.
