Abstract
An apparatus includes a substrate having a recess and a multitude of particles arranged in the recess. A first portion of the particles is joined to a porous structure by means of a coating. A second portion of the particles is not joined by means of the coating. The first portion of the particles is arranged closer to an opening of the recess than the second portion of the particles so that a leaking of the second portion of the particles from the recess through the opening is prevented.
Claims32
An apparatus comprising:
- a substrate comprising a recess;
- and
- a multitude of particles arranged in the recess;
- wherein a first portion of the particles is joined to form a porous structure by means of a coating, and wherein a second portion of the particles is not joined by means of the coating;
- and
- wherein the first portion of the particles is arranged closer to an opening of the recess than the second portion of the particles so that a leaking of the second portion of the particles from the recess through the opening is prevented;
- wherein the particles of the second portion are configured to react with a fluid and/or to bind the fluid or a substance thereof;
- wherein the second portion comprises a number of particles which is greater than a number of particles of the first portion by a factor of at least 1.1;
- and
- wherein the apparatus comprises at least one electrode structure which is in contact with the multitude of particles and is configured to sense an electric potential of the particles in contact with the electrode structure, or to apply the electric potential to the particles in contact with the electrode structure;
