  • Patent number: 9157115
    Abstract: The present invention relates to aptazyme sensor devices comprising, in addition to the aptamer, ribozyme and communication components, a competitive inhibitory component with a metal nanoparticle or a competitive inhibitory and signalling component with a metal nanoparticle and a label, such that the enzymatic activity of the ribozyme is inhibited as long as the inhibitory or the inhibitory and signalling component is bound to the substrate binding site of the ribozyme. The aptazyme sensor devices of the invention have increased shelf-life and are suitable for the parallel detection of different ligands by using an array of aptazyme sensor devices utilizing inhibitory and inhibitory and signalling components with different metal nanoparticles. The present invention furthermore relates to the post-synthetic chemical modification of the aptamer component for avoiding unspecific binding.

  • Publication number: 20130064423
    Abstract: Feature extraction includes extracting features from signals of a plurality of sensors of a sensor array, including, for each sensor, obtaining a signal of the sensor corresponding to responses of the sensor during one or more exposures to samples, computing a baseline function from the signal, and computing the features based on the baseline function and values corresponding to responses of the sensor during each exposure. Feature vectors are formed from the features of the sensors. The features in each feature vector correspond to the same exposure. At least one of computing the baseline function by interpolating baseline values corresponding to responses of the sensor prior to each exposure, and forming the feature vectors by combining features of at least one sensor with features of at least one redundant sensor of the sensor array in the feature vectors is performed.
