Batch microfabrication of highly integrated silicon-based electrochemical sensor and performance evaluation via nitrite water contaminant determination

The fabrication of a chemical sensor with PANI-TiO2 nanocomposites

“…Similar results have been reported by earlier authors in the detection of toxic chemicals using the electrochemical (I-V) approach. [28][29][30][31][32][33] As per the authors' knowledge, the GCE with the synthesized PANI-TiO 2 NPs is the rst 1,2-DAB sensor to apply the I-V approach in phosphate buffer phase. The holding time in the Keithley electrometer was set as 1.0 s throughout the experiment.…”

Connected Sensors, Innovative Sensor Deployment, and Intelligent Data Analysis for Online Water Quality Monitoring

“…The choice of materials and eventually the sensor performance, depends on their structural properties. For example, nanostructured materials exhibit high surface to volume ratio, and hence the fast response and high sensitivity [20,[78][79][80]. In addition, the shape or morphology of the nanomaterial could influence the sensor performance [81,82].…”

“…A vast majority of reported works based on thin film-based Ag/AgCl REs show drift [99,100]. To solve this issue, solidstate Ag/AgCl electrode could be placed in a mini tank of KCl solution for better ion exchange, as done in the case of nitrite monitoring sensor [20], and the outcome was a stable potential with very small variation of 2 mV. The design of this sensor shows potential usefulness for monitoring of analytes such as phosphates and ammonium.…”

“…Over the last decade, the WQ observing technology has risen to the challenge of scientists and has provided them with tools that identify poor WQ by autonomously measuring the essential PCB parameters [11][12][13][14][15][16][17][18][19][20][21]. Sensorised buoys and boats have been deployed for data collection and in situ-monitoring [22][23][24][25][26][27][28].…”

Integration of Different Graphene Nanostructures with PDMS to Form Wearable Sensors

“…These silicon sensors were formed using microelectromechanical system (MEMS) techniques that consisted of techniques such as conventional photolithography [ 10 , 11 ] to form the designated electrodes. Although these sensors were used for different environmental [ 12 , 13 ] and gas-sensing [ 14 , 15 ] applications, some disadvantages were associated with their fabrication cost. One of the primary disadvantages is that the development of these sensors requires very expensive cleanrooms and foundry facilities, thus increasing the assembly cost even for a few sensors [ 16 , 17 ].…”
