The Flexible Urea Biosensor Using Magnetic Nanoparticles
Source abstract
Abstract
A flexible urea sensor based on urease-magnetic beads (MBs) and graphene oxide (GO) has been synthesized on nickel oxide (NiO) as matrix. The flexible urea sensor was constructed by sputtering technology and screen-printing technology. A sequential titrating of GO and MBs over the surface on NiO film was adopted for the sensor preparation by the covalent binding with urease. The electrochemical impedance, response time, and drift effect of the urea sensor based on MBs, GO, and NiO were recorded using electrochemical impedance spectroscopy and voltage-time measurement system.
