Abstract
A sensor element useful in making fluorescence-optical measurements includes a substrate having a carrier surface, particles having a large specific surface are which are glued, melted or sintered onto the carrier surface so as to provide small elevations of a regular distribution on the carrier surface, and an indicator substance immobilized on the particles. Additional substances can be applied to the particles to reduce undesirable influences of properties of the sample on the indicator substance.
