| 摘要 |
The present invention provides a luminescence sensor (2), such as e.g. a luminescence biosensor, comprising a multi-layer structure. The multi-layer structure comprises at least a first layer (2a) formed of a first material and a second layer (2b) formed of a second material. The first material has a first binding capacity towards luminophores and the second material has a second binding capacity towards luminophores, the first binding capacity being different from the second binding capacity. The luminescence sensor (2) according to the present invention shows a high sensitivity because it provides preferred binding sites for luminophores at locations where the combined excitation and detection efficiency is the highest.
