Nanosensors are chemical or mechanical sensors that can be used to detect the presence of chemical species and nanoparticles, or monitor physical parameters such as temperature, on the nanoscale. They ...
Abstract: Optical dissolved oxygen (DO) concentration measurement based on phase fluorometric theory is one of the most promising DO concentration measurement methods with advantages of insensitivity ...
Abstract: A microfluidic electrochemical sensor is fabricated for the measurement of chemical oxygen demand (COD) in surface waters, such as lakes and reservoirs. An Au interdigital electrode is used ...
