We describe an electrochemical sensor assay method for rapid bacterial detection and identification. The assay involves a sensor array functionalized with DNA oligonucleotide capture probes for ribosomal RNA (rRNA) species-specific sequences. Sandwich hybridization of target rRNA with the capture probe and a horseradish peroxidase-linked DNA oligonucleotide detector probe produces a measurable amperometric current.

Quantitative, high-throughput, real-time, and label-free biomolecular detection (DNA, protein, etc.) on SiO2 surfaces can be achieved using a simple interferometric technique which relies on LED illumination, minimal optical components, and a camera. The Interferometric Reflectance Imaging Sensor (IRIS) is inexpensive, simple to use, and amenable to microarray formats.

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University The glovebox provides a straightforward means to handle air- and moisture-sensitive solids and liquids. The glovebox is what it sounds like: a box with gloves attached to one or more sides, which allows the user to perform manipulations within the glovebox under an inert atmosphere. For manipulations under inert atmospheres, chemists can choose between Schlenk or high-vacuum techniques and a glovebox. Schlenk and...
FAQs
Passive systems read variations in infrared energy emitted by warm bodies, so changes in detected radiation can indicate presence or movement without illuminating the subject. Active systems instead send infrared light and analyze its reflection or interruption. The choice affects what the signal represents: emitted-energy changes in one case, and interaction with transmitted light in the other.
After detection, the sensor signal can be converted into behavioral measures such as movement, proximity, or activity. This conversion is important because raw infrared changes are not themselves a complete behavioral description; they become interpretable observations when linked to the event being monitored. In this way, the same sensing principle can support different measurements of behavior.
Automated recording reduces reliance on a human observer to notice and score events. Because the system can monitor continuously, it can capture activity across the observation period rather than only selected moments. This supports more consistent comparisons of locomotion, spatial patterns, social interactions, or responses to experimental conditions, while keeping measurement separate from subjective visual judgment.
A behavioral workflow begins by selecting passive or active detection according to whether emitted infrared variation or reflected or interrupted light is the relevant signal. The system then records the infrared response and converts it into movement, proximity, or activity data. Researchers can analyze those measures in relation to locomotion, spatial position, interactions, or experimental responses.
Infrared Sensor Detection can be applied in laboratory and field settings when researchers need measurements without direct contact. That feature is useful for observing behavior while minimizing interference from handling or close observation. The resulting records can support continuous assessment of locomotion, spatial patterns, social interactions, and changes associated with an experimental condition.
Continuous monitoring allows researchers to follow activity throughout an observation period and examine changes linked to experimental conditions. Rather than relying only on isolated observations, they can evaluate patterns in locomotion, spatial behavior, or interactions as they occur. This broader record can make behavioral comparisons more consistent and helps reveal responses that might otherwise be missed.
