METHOD AND DEVICE FOR IDENTIFYING A POLYMER SEQUENCE
First Claim
1. A device for identifying a first polymer sequence, wherein said first polymer sequence is bound to a label made of a metal foil which can be firmly linked to an object to be labeled, wherein said label made of a metal foil reflects electromagnetic waves, said device comprising a second polymer sequence bound to a phase via metallic clusters, wherein said phase is permeable to electromagnetic waves, wherein said device can be brought into contact with a labeled object, wherein when said first polymers and said second polymers are brought into contact with one another and are complementary to one another, a distance is established between the metal foil and the metallic clusters that results in an observable change in the optical property of the electromagnetic waves, wherein said change in optical property is a spectral shift, wherein when said first polymers and said second polymers are not complementary to one another, a distance is not established between the metal foil and the metallic clusters and does not result in the spectral shift.

Abstract
The invention relates to a method for identifying a first polymer sequence bound to a first phase that reflects electromagnetic waves. The inventive method includes the following steps: a) bringing the first polymer sequence into contact with an affine second polymer sequence, which is directly or indirectly bound, via metallic clusters, to a solid second phase that is permeable to electromagnetic waves; b) radiating electromagnetic waves through the second phase, and; c) detecting the alteration of the properties of the reflected electromagnetic waves.
