Abstract:
The present application refers to a method of patterning organic materials or organic/inorganic materials onto a substrate, comprising the following steps: (1) patterning of a water-soluble material “A” onto a surface of the substrate, thereby forming a substrate/material “A” surface; (2) depositing organic or organic/inorganic material “B” onto the substrate/material “A” surface; (3) lifting-off material “A” in aqueous solution; wherein, step (1) comprises the following steps: (1a) patterning of a photoresist material onto the substrate surface, thereby forming a substrate/photoresist material surface; (1b) depositing the water soluble material “A” onto the substrate/photoresist material surface; (1c) lifting-off the photoresist material in an organic solvent; or, alternatively, step (1) comprises the following steps: (1a′) depositing the water-soluble material “A” onto the substrate surface, thereby forming a substrate/material “A” surface; (1b′) patterning the photoresist material onto the substrate/material “A” surface; (1c′) etching the unmasked material “A” in aqueous solution; (1d′) lifting-off the photoresist material in an organic solvent. The present application also refers to the use of said method, to a pattern of organic materials or organic/inorganic materials prepared by said method, and to a substrate carrying such patterns. The application also refers to the use of a patterned nanoparticle film.

Abstract:
An e-nose device employing chemiresistive sensors with a thin nanoparticle film allows to perform a fast and accurate analysis of respiratory gases during anesthesia in real-time over the entire breathing cycle. A combinatorial selection of nanoparticles and organic linker molecules in the nanoparticle film allows to achieve a high selectivity, which is particularly suitable for detecting a change of anesthetics or analgesics over time.

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.
