Abstract: The present disclosure relates to the identification of components in a sample based on the chemical nature of the component. In particular, although not exclusively, the present disclosure relates to the identification of hydrophobic and hydrophilic components using a mass spectrometric technique. The present invention also relates to kits and products used in the identification of the components, as well as other subject matter.

Abstract: A method of preparing hydrophobic silica particles includes the step of reacting together in a single step a mixture of silane ether monomers and organically modified silane ether monomers with a hydrolyzing agent. The method also includes producing hydrophobic silica microparticles and nanoparticles that can include dyes and/or magnetizable components. The silica nanoparticles can be used in the detection, visualization and/or analysis of latent fingerprints.

Abstract: The present invention is directed to a method for determining the presence of a residue on or within a fingerprint using matrix-assisted mass spectrometric techniques. The matrix-assisted mass spectrometric technique can be selected from Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Time-Of-Flight Mass Spectrometry (MALDI-TOF-MS) and/or Surface Assisted Laser Desorption/Ionisation Time-Of-Flight Mass Spectrometry (SALDI-TOF-MS).

Abstract: The present invention provides a method for simultaneously detecting the presence of at least two enzymes in a sample. The method includes the steps of: i) providing a first substrate for a first enzyme, the first substrate being labeled with a first fluorophore; ii) providing a second substrate for a second enzyme, the second substrate being labeled with a second fluorophore; iii) exposing the labeled substrates to the sample to allow the first and second enzymes present in the sample to interact with respective first and second fluorophore-labeled substrates to form respective first and second fluorophore-labeled substrate fragments; and iv) detecting the presence of the fluorophore-labeled substrate fragments.

Abstract: There is described an affinity-chromatography assay system comprising with an immobilised component containing a bio-reagent and a flowable component containing a complimentary bio-reagent characterised in that the immobilised component is supported on a dip strip or planar surface and the flowable component is adapted to flow down the dip strip of high density. There is also described a method of conducting an affinity-chromatography assay which comprises the use of such an assay system.
