Sub-Nanoliter Spectroscopic Gas Sensor
In this work, a new type of optical fiber based chemical sensor, the sub-nanoliter sample cell (SNSC) based gas sensor, is described and compared to existing sensors designs in the literature. This novel SNSC gas sensor is shown to have the capability of gas detection with a cell volume in the sub-nanoliter range. Experimental results for various configurations of the sensor design are presente...
متن کاملSub-ppm multi-gas photoacoustic sensor.
A photoacoustic multi-gas sensor using tuneable laser diodes in the near-infrared region is reported. An optimized resonant configuration based on an acoustic longitudinal mode is described. Automatic tracking of the acoustic resonance frequency using a piezo-electric transducer and a servo electronics is demonstrated. Water vapour, methane and hydrogen chloride have been measured at sub-ppm le...
متن کاملMeasuring Liquid Volumes in Sub-nanoliter Wells
We are developing a method for high-throughput screening using arrays of “nanowells” built into a silicon substrate. These wells can serve as bioreactors for studying a variety of biochemical reactions such as the enzymatic activity that occurs in yeast metabolism. For a variety of studies it is important to know the volume of liquid that has been deposited in a given well and/or to monitor the...
متن کاملFluorescence detection in (sub-)nanoliter microarrays
The goal of our TU Delft interfaculty research program is to develop intelligent molecular diagnostic systems (IMDS) that can analyze liquid samples that contain a variety of biochemical compounds such as those associated with fermentation processes. One speci c project within the IMDS program focuses on photon sensors. In order to analyze the liquid samples we use dedicated microarrays. At thi...
متن کاملLaser Spectroscopic Trace-Gas Sensor Networks for Atmospheric Monitoring Applications
Laser-based atmospheric trace-gas sensors have great potential for long-term, real-time, maintenance free environmental monitoring in distributed Wireless Sensor Networks (WSN). We are developing a laser based chemical sensing technology with wide-area autonomous wireless sensor networking as the final target. Our prototype sensor measures atmospheric oxygen concentration in the form of a batte...
