  2. Molecular sensor - Wikipedia

    en.wikipedia.org/wiki/Molecular_sensor

    The term supramolecular analytical chemistry has recently been coined to describe the application of molecular sensors to analytical chemistry. [25] Small molecule sensors are related to chemosensors. However, these are traditionally considered as being structurally simple molecules and reflect the need to form chelating molecules for ...

  3. Bio-layer interferometry - Wikipedia

    en.wikipedia.org/wiki/Bio-layer_interferometry

    Bio-layer interferometry platforms achieve high throughput by utilizing a "Dip and Read" format. [1] The biosensor tips themselves are transported directly to the desired sample and "dipped" into their respective compartment, eliminating the needs for micro-fluidics and the complications (clogging, purification) that come with it.

  4. Safety reflector - Wikipedia

    en.wikipedia.org/wiki/Safety_reflector

    A rear reflector on a bicycle Reflecting device on horse. A safety reflector is a retroreflector intended for pedestrians, runners, motorized and non-motorized vehicles. A safety reflector is similar to reflective stripes that can be found on safety vests and clothing worn by road workers and rescue workers. They are sometimes erroneously ...

  5. Biosensor - Wikipedia

    en.wikipedia.org/wiki/Biosensor

    Surface plasmon resonance sensors operate using a sensor chip consisting of a plastic cassette supporting a glass plate, one side of which is coated with a microscopic layer of gold. This side contacts the optical detection apparatus of the instrument. The opposite side is then contacted with a microfluidic flow system.

  6. Reflectometric interference spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Reflectometric...

    Through chemical modification the upper SiO 2 layer is changed in a way to allow interaction with target molecules. This interaction causes a change in the thickness of the physical layer d and the refractive index n within this layer. The product of both defines the optical thickness of the layer: n • d.

  7. Chemiresistor - Wikipedia

    en.wikipedia.org/wiki/Chemiresistor

    Simplified schematic of a single gap chemiresistive sensor. (not to scale) A chemiresistor is a material that changes its electrical resistance in response to changes in the nearby chemical environment. [1] Chemiresistors are a class of chemical sensors that rely on the direct chemical interaction between the sensing material and the analyte. [2]

  8. Bioinstrumentation - Wikipedia

    en.wikipedia.org/wiki/Bioinstrumentation

    The National Aeronautics and Space Administration (NASA) have developed telemetric sensors in order to monitor physiological changes in animal models in space in their Sensors 2000! program. These sensors measure physiological measurands, including temperature, biopotentials, pressure, flow and acceleration, chemical levels, and transmit these ...

  9. Non-invasive micro-test technology - Wikipedia

    en.wikipedia.org/wiki/Non-invasive_Micro-test...

    An NMT H + flux profile of Arabidopsis root across several zones. This example shows strong H + influx closer to the root tip, and slight H + efflux further from the tip.. Non-invasive micro-test technology (NMT) is a scientific research technology used for measuring physiological events of intact biological samples.
