  • Production of graphene structures
    Publication number: 20210316992
    Abstract: According to an example aspect of the present invention, there is provided a method for producing graphene foam structures by assembling graphene or graphene oxide in a three-dimensional structure, wherein biomolecular surface active agents are used as a template in a water-based foam. The graphene foam structures produced by the method of the invention find industrial application for example in sensing and material applications.

  • Detection of cannabis use
    Patent number: 8518653
    Abstract: A binding partner, especially an antibody fragment that specifically recognizes an antigen-antibody immune complex between anti-THC and THC (tetrahydrocannabinol), is disclosed. The binding partner facilitates a non-competitive homogenous immunoassay for detection of cannabis use. A test kit comprising the binding partner is also described. Preferably the immunoassay is applied for roadside testing of saliva from suspected drivers.

  • Non-competitive immunoassay for small analytes
    Patent number: 7749712
    Abstract: A non-competitive immunoassay for small analytes, wherein the analyte is reacted with two binding partners. The first binding partner binds to the analyte to form a complex between the first binding partner and the analyte, and the second binding partner binds to the complex formed by the first binding partner and the analyte. The resulting complex formed between the analyte and the binding partners is detected. The binding partners are proteins, such as antibodies including antibody fragments.
