Abstract (en)
[origin: WO2005033674A1] The invention relates to a method for detecting particles that are contained in an aqueous solution, the size of said particles lying in the nanometre range (nanoparticles), whereby said detection does not take place by means of a specific bond between proteins and/or nucleic acids in the nanoparticles. According to the method, biomolecules, in particular peptides, which bond specifically with the substance and thus with the nanoparticles are obtained. Said biomolecules are immobilised on the surface of a sensor, which is suitable for detecting a mass-dependent size, the aqueous solution of nanoparticles being conducted over the surface of the sensor and a signal of the latter being registered. The surface of the sensor is then flushed with a standard solution and the modification to the signal is registered. The nanoparticle quantity N(a) is determined from the course of the sensor signal.
