摘要： A method for determining the presence of a compound in a liquid solution, by admixing the liquid solution with a plurality of nanoparticles; providing conditions effective to cause aggregation of the nanoparticles in the liquid solution in the absence of said compound in the liquid solution; and observing a detectable signal reflecting the amount of aggregation of nanoparticles in the liquid solution, wherein the presence of the compound in the liquid solution results in a detectable signal reflecting a reduced amount of aggregation of nanoparticles in the liquid solution, in comparison to the amount of aggregation of nanoparticles obtained in the liquid solution in the absence of the compound therein. A nanoparticle, a composition, a kit and a for multi-well plate for use in the method are also disclosed. In some embodiments the association is cation-, anion and/or PH induced e.g. by using helix-loop-helix polypeptides as first and second molecules attached to the nanoparticles. The first molecules are directed to the target compound, the second molecules allow for aggregation of the nanoparticles.

摘要： A coated metal surface on a solid support, wherein the coating consists of a self-assembled monolayer (SAM) of oligo(ethylene glycol)-terminated amide group-containing alkyl thiols firmly attached to the metal surface via the thiol-end and low molecular weight antigens bound via an amide-group to the SAM-forming OEG molecule, wherein the alkyl portion has 1-20 methylene groups, wherein the oligo(ethylene glycol) portion has 1-15 ethylene oxy units, and wherein the antigens, such as explosives and narcotics, are optionally reversibly bound to antibodies specific for the antigens, is disclosed. The coated metal surface on a solid support may be used in a method of detecting analyte antigens as part of an analysis device, such as a Piezoelectric Crystal Microbalance device or a Surface Plasmon Resonance biosensor, for detection in an aqueous solution of an analyte antigen with higher affinity to an antibody than the antigen of the coating by monitoring the displacement of the antibody from the coating.
