Abstract: The invention provides protein-functionalized magnetic nanoparticles comprising magnetic nanoparticles (MNPs) to which a lactose-binding protein or enzyme has been immobilized. The protein-functionalized magnetic nanoparticles are particularly suitable for separating lactose from a lactose-containing solution, such as milk, cheese, yoghurt, flavored milk or the like. The protein-functionalized MNPs can be added to the lactose-containing solution and be allowed to bind to the lactose in the solution. The MNPs, to which the lactose is bound, can then be magnetically removed from the solution, e.g. by applying an external magnetic field.

Abstract: A method and a detection device for detecting endocrine disrupting compounds are provided. The detection device includes a support structure and ligand binding domains (LBD) of at least one sex hormone receptor, immobilised on the support structure. The detection device further includes a linker molecule between the support structure and the ligand binding domains, for immobilising the LBD's on the support structure.

Abstract: The invention relates to an apparatus suitable for equalizing a spectrum of a broadband light source comprising a first optical path and a second optical path; an optical splatter being connectable to an optical power source, for directing at least part of optical power from the optical power source to each of the first and second optical paths; an optical filter provided in the first optical path for filtering the optical signal propagating there through; and an optical combiner for combining at least part of the optical signals from each of the first and second paths into an output channel. Preferably, the optical splitter is tuneable to direct at least part of the optical power from the optical source to each of the first and second paths, in varying proportions.
