The invention relates to a method for forgery-proof labeling of items, such as credit cards, bank notes and the like, comprising the following steps: (a) applying, to a first layer () that reflects electromagnetic waves, an inert second layer () that is permeable to electromagnetic waves, said second layer having a predetermined thickness, (b) applying, to said second layer (), a third layer () that is formed by metal clusters, and (c) linking the first layer () of the label so produced with the item.

Method for forgery-proof labeling of items, and forgery-proof label

A device for the electrochemical detection of at least one biochemical molecule contained in a liquid from a group of predetermined biochemical molecules includes a holder () for taking up the liquid, with at least one reference electrode (RE) and at least one counterelectrode (GE) and a multiplicity of working electrodes (AE, AE, AE). At least one working electrode is provided for the detection of each biochemical molecule, and is coated with a molecule that is complementary to the respective biochemical molecule, so that the biochemical molecules can be detected simultaneously. The device includes a potentiostat (P) for generating a predetermined voltage profile between the working electrodes and the reference electrode, a current/voltage converter (S, S, S) connected downstream of each of the working electrodes for holding all of the working electrodes at the same potential, and a measurement device (Ad) for measuring the currents flowing through the working electrodes.

Electrochemical detection method and device

The invention relates to a method for identifying a first polymer () which is bonded to a first phase () that reflects electromagnetic waves. Said method comprises the following steps: (a) bringing the first polymer () into contact with a second polymer (), which is bonded to a solid second phase () by metallic clusters (), said second phase being permeable to electromagnetic waves; (b) irradiating the second phase () with electromagnetic waves; and (c) determining the change in the properties of the reflected electromagnetic waves.
