Abstract: A fiber-optic urea sensor based on surface plasmon resonance (SPR) and Mach-Zehnder interference (MZI) combined principle was designed and implemented. By plating gold film on the ...
Study on the disposable urea biosensors based on PVC-COOH membrane ammonium ion-selective electrodes
Abstract: A potentiometric urea biosensor is prepared by the immobilization of urease directly onto the surface of a solid-state ammonium ion-selective electrode. The enzyme is immobilized by ...
