Two types of urea biosensors were integrated with a wireless measurement system and microfluidic measurement system. The two biosensors used were (i) a magnetic beads (MBs)-urease/graphene oxide (GO)/titanium dioxide (TiO)-based biosensor and (ii) an MBs-urease/GO/ nickel oxide (NiO)-based biosensor, respectively. The wireless measurement system work exhibited the feasibility for the remote detection of urea, but it will require refinement and modification to improve stability and precision.

- The study introduces a flexible lactate biosensor utilizing l-lactate dehydrogenase and NAD+ immobilized on a nickel oxide film, enhanced by graphene oxide and magnetic beads for better performance.
- The biosensor shows impressive sensitivity of 45.397 mV/mM and a high linearity of 0.992 within the lactate concentration range of 0.2 mM to 3 mM.
- Electrochemical impedance spectroscopy results indicate that the modified biofilm has superior electron transfer efficiency compared to other configurations, and additional tests confirm its detection limits and resilience.
