Printed 384‐Well Microtiter Plate on Paper for Fluorescent Chemosensor Arrays in Food Analysis
Chemistry – An Asian Journal, 2022AbstractWe propose a printed 384‐well microtiter paper‐based fluorescent chemosensor array device (384‐well microtiter PCAD) to simultaneously categorize and discriminate saccharides and sulfur‐containing amino acids for food analysis. The 384‐well microtiter PCAD requiring 1 μL/4 mm2 of each well can allow high‐throughput sensing.

Supramolecular hydrogel-based protein and chemosensor array
Lab on a Chip, 2010The development of protein and sensor arrays is crucial for rapid and high-throughput assays of biological events, markers, environmental pollutants, and others. We describe supramolecular hydrogel as a unique material for use as a matrix for immobilizing proteins, peptides, substrates, chemosensors, and mesoporous silica particles, and thereby array ...

We herein propose an easy-to-prepare mini-chemosensor array constructed by two-types of off-the-shelf coumarin dyes for simultaneous classification and quantification of sulfur-containing amino acids (SCAAs) (i.e., l-cysteine, l-cystine, l-homocysteine, glutathione, and glutathione disulfide).

A cross-reactive chemiluminescence (CL) sensor array based on catalytic nanomaterials was constructed for the discrimination and identification of flavors in cigarettes. A total of 21 nanomaterials, including metal oxides, metal oxides deposited on carbon nanotubes (CNTs), gold nanoparticles deposited on metal oxides, and carbonate, have been carefully

Increasing the separability of chemosensor array patterns with Hebbian/anti-Hebbian learning
Sensors and Actuators B: Chemical, 2006The olfactory bulb is able to enhance the contrast between odor representations through a combination of excitatory and inhibitory circuits. Inspired by this mechanism, we propose a new Hebbian/anti-Hebbian learning rule to increase the separability of sensor-array patterns in a neurodynamics model of the olfactory system: the KIII.

Simple, rapid, and accurate detection methods for saccharides are potentially applicable to various fields such as clinical and food chemistry. However, the practical applications of on-site analytical methods are still limited. To this end, herein, we propose a 96-well microtiter plate made of paper as a paper-based chemosensor array device (PCSAD ...

Contrast enhancement and background suppression of chemosensor array patterns with the KIII model
International Journal of Intelligent Systems, 2006Summary: Inspired by the ability of the olfactory bulb to enhance the contrast between odor representations, we propose a new Hebbian learning rule that is able to increase the separability of odor patterns from gas sensor arrays. The proposed learning rule employs a Hebbian term to build associations within odors and an anti-Hebbian term to reduce ...

Application-specific design of a piezoelectric chemosensor array
Sensors and Actuators B: Chemical, 1992Abstract A piezoelectric quartz sensor array with non-selective but different sensitive coating materials is used for the analysis of anaesthetic gases. Several gas-sensitive quartz resonators can be composed into an array and the sensor signals can be handled by pattern-recognition (PARC) methods.

CuO–ZnO Micro/Nanoporous Array‐Film‐Based Chemosensors: New Sensing Properties to H2S
Chemistry – A European Journal, 2014AbstractCuO–ZnO micro/nanoporous array‐films are synthesized by transferring a solution‐dipped self‐organized colloidal template onto a device substrate and sequent heat treatment. Their morphologies and structures are characterized by X‐ray diffraction, field‐emission scanning electron microscopy, transmission electron microscopy, and X‐ray ...

The surface-enhanced Raman scattering from ZnO nanorod arrays and its application for chemosensors
Sensors and Actuators B: Chemical, 2014Abstract Based on the surface-enhanced Raman scattering (SERS) of two similar probe molecules, 4-mercaptopyridine (4-MPY) and 4-aminothiophenol (PATP) from the ZnO nanorod arrays (ZnONRs) substrates, the prerequisite of SERS for ZnONRs-molecules system was investigated.
