There is disclosed a method for partially derivatizing a curved surface of particles in an electrically conducting solvent, said method comprises the steps: a) bringing particles in close contact with at least one surface by using a force, b) inducing a chemical reaction on at least one part of a particle by applying an electrical potential between said at least one surface and the electrically conducting solvent, and c) further reacting said at least one part of a particle where a chemical reaction has been induced in step b) above. There is further disclosed a partially derivatized particle as well as uses of the particle. Advantages include that the method is simple and only requires a potentiostat in addition to standard laboratory equipment, is inexpensive, time-efficient, and inherently parallel.

Partial derivatization of particles

A novel detection or quantifying method for biological entities or molecules such as, but not limited to, DNA, microorganisms and pathogens, proteins and antibodies, that by themselves are target molecules or from which target molecules are extracted, comprises the steps of i) forming target molecule-dependent volume-amplified entities, ii) allowing magnetic nanoparticles to bind to said volume-amplified entities, and iii) measuring changes in dynamic magnetic response of the magnetic nanoparticles caused by the increase in hydrodynamic volume of said magnetic nanoparticles.
