The fabrication and characterisation of an integrated microfluidic chip for phosphate detection are described. A micro three-electrode-system embedded in a microfluidic channel was used for the analysis of samples. Working electrodes and counter electrodes were arranged as an interdigitated array to increase the current response. Owing to the nonlinear diffusion effect of ultra-microelectrodes and...
This paper presents the design of a novel microelectromechanical system (MEMS)-based total phosphorus (TP) microsensor with a microdigestion system. Cobalt metal film is introduced as the sensing material of the microelectrodes, and a micro digestion bioreactor is used as the microdigestion unit. The sensing mechanism of the cobalt electrodes to the concentration of phosphate ions is demonstrated...
