  • Patent number: 9958439
    Abstract: The present invention relates to a method for detection, identification and/or quantification of one or more carbohydrates. The method comprises the steps of contacting an objector a sample with a luminescent conjugated oligothiophene (LCO) and detecting at least one detection signal of the luminescent conjugated oligothiophene. The presence of and/or the identity of and/or the quantity of one or more carbohydrates that is or are present on said object or in said sample is determined based on said detected detection signal from the LCO. The invention encompasses methods for carbohydrate detection by use of oligothiophene derivatives. The methods are quick, easy and direct and can be performed in real time as well as in situ.

  • Publication number: 20130210070
    Abstract: A microfiuidic device comprises a valve having electrically controllable wetting properties. The valve comprises a valve surface arranged in a closed valve space defined by at least the valve surface, a first liquid opening for leading a first liquid to the valve and a second liquid opening for leading a second liquid to the valve. The valve surface, in a first state, is sufficiently hydrophobic to prevent contact between the first liquid and the second liquid. The valve surface, in a second state, is sufficiently hydrophilic to allow contact between the first liquid and the second liquid. A ventilation outlet is provided for allowing gas to escape from the valve space.

  • Publication number: 20130078701
    Abstract: The present disclosure relates to a device comprising a conductive substrate surface (19), at least one layer of a conductive polymer (14) deposited on the surface (19), a first electrolyte (13) arranged in contact with the conductive polymer layer, and a counter electrode (11), arranged in contact with the first electrolyte (13), such that a potential difference can be applied between the conductive substrate (15) and the counter electrode (11). The conductive polymer (14), in a first state, before applying the potential difference, exhibits a first adhesive capacity, wherein the conductive polymer layer (14) is substantially attached to the conductive substrate surface (19). In a second state, subsequent to application of the potential difference, the conductive polymer (14), exhibits a second adhesive capacity, such that at least a portion of the conductive polymer layer (14) is substantially released from the conductive substrate surface (19).

  • Patent number: 8137524
    Abstract: A device is disclosed for electrically controlled transport of ions between a source and a target electrolyte, including a source electrode and a target electrode. The electrodes are each capable of conducting ions, and the source electrode is arranged to receive ions from the source electrolyte and the target electrode is arranged to release ions to the target electrolyte. The device further includes an ion-conductive channel, arranged to receive ions from the source electrode and to release ions to the target electrode. Moreover, the ion-conductive channel is arranged to provide an ionic connection between the source and the target electrodes. The electrodes and the ion-conductive channel are formed of solid or semi-solid materials which are directly or indirectly attached to a support.
