  Described herein are nanoparticles that are coated with a bilayer of molecules formed from surface binding molecules and amphiphatic molecules. The bilayer coating self assembles on the nanoparticles from readily available materials/molecules. The modular design of the bilayer coated nanoparticles provides a means for readily and efficiently optimizing the properties of the bilayer coated nanoparticle compositions. Also described herein are uses of such nanoparticles in medicine, laboratory techniques, industrial and commerical applications.

  The present invention relates to a probe compound that can comprise any substrate or metabolite of an enzymatic reaction in addition to an indicator component, such as, for example, a fluorescence dye, or the like. Moreover, the present invention relates to means for detecting enzymes in form of an array, which comprises any number of probe compounds of the invention which each comprise a different metabolite of interconnected metabolites representing the central pathways in all forms of life. Moreover, the present invention relates to a method for detecting enzymes involving the application of cell extracts or the like to the array of the invention which leads to reproducible enzymatic reactions with the substrates. These specific enzymatic reactions trigger the indicator (e.g. a fluorescence signal) and bind the enzymes to the respective cognate substrates. Moreover, the invention relates to means for isolating enzymes in form of nanoparticles coated with the probe compound of the invention. The immobilisation of the cognate substrates or metabolites on the surface of nanoparticles by means of the probe compounds allows capturing and isolating the respective enzyme, e.g. for subsequent sequencing.

  Multivalent binding compositions including a particle-nucleotide conjugate having a plurality of copies of a nucleotide attached to the particle are described. The multivalent binding compositions allow one to localize detectable signals to active regions of biochemical interaction, e.g., sites of protein-protein interaction, protein-nucleic acid interaction, nucleic acid hybridization, or enzymatic reaction, and can be used to identify sites of base incorporation in elongating nucleic acid chains during polymerase reactions and to provide improved base discrimination for sequencing and array based applications.
