The purpose of this study was to determinate ofloxacin, the approach of electrospinning and electrochemical was adopted, metal oxide cobalt tetroxide (Co3O4)/graphene (GR) nanomaterials were electrodeposited on the surface of glassy carbon electrode, then prepared a new type of nanocomposite electrode (Co3O4/GR/GCE), it was successfully used to measure ofloxacin. The experiments show that the surface morphology of the modified electrode was characterized by scanning electron microscopy, and the Co3O4 nanoparticles and GR could be well modified on the surface of the glassy carbon electrode. The determination conditions of ofloxacin were optimized by the differential pulse voltametry (DPV). Under the optimal conditions, the linear relationship ranged from 0.45 to 170 μM, and the minimum detection limit was 0.16 μM (S/N = 3). Moreover, the recovery rate in the actual drug was good, and the relative standard deviations were all less than 5%. The impacts of the obtained results indicate that the modified electrode has good electrocatalytic performance for ofloxacin, and has good repeatability and practicability, and can significantly improve the detection sensitivity.

“…Similar to glucose detection, NiOOH/Ni(OH) 2 redox couple is demonstrated for H 2 O 2 sensing when Ni-based nanomaterials are used as nonenzymatic active materials. There are numerous examples of Ni-based nonenzymatic glucose and H 2 O 2 sensors constructed by modifying the substrate with nickel nanoparticles, nickel–carbon hybrids, Ni–CNT composite, Ni–graphene composites, Ni(OH) 2 /C nanoparticles, LaNiO 3 nanooxide, etc. ,− It has also been demonstrated that the sensor characteristics may simply be tuned via doping the electrochemically active thin films. For instance, Ding et al fabricated a novel amperometric nonenzymatic glucose sensor based on Au doped NiO nanobelts .…”

People with diabetes require regular blood sugar level monitoring, using commercial enzyme-based biosensors. There is a considerable need to develop biosensors with nonenzymatic electrodes to eliminate the drawbacks of enzymes. Nanostructured nickel oxide (NiO) thin films are highly promising materials for the development of nonenzymatic glucose and hydrogen peroxide (H 2 O 2 ) biosensors. Although the biosensor performance can be easily attained with nonenzymatic electrodes, their commercialization still requires development of cost-effective and mass-production methods. In this work, we demonstrate the use of ultrasonic spray deposited, nanometer-thick, manganese and cobalt doped NiO (Mn:NiO and Co:NiO) films on indium tin oxide (ITO) coated glass substrates for glucose sensing. Sensor characterization followed detailed materials characterization. Nanometer-thick Co:NiO film electrodes showed better glucose sensor performance than those of bare NiO and Mn:NiO electrodes. High sensitivity of 1.67 μA/μM•cm 2 , a low detection limit of 231 nM, and a fast response time of 5.4 s within the linear range of 16−308 μM were obtained from nanometer-thick Co:NiO film electrodes. Amperometric measurements showed significant electrode reproducibility and stability. Nanometer-thick Co:NiO film electrode was also used to demonstrate actual clinical glucose measurements using human blood serum as a glucose source. Moreover, all fabricated nanometer-thick film electrodes were also utilized as H 2 O 2 sensors. This work provides a novel approach for monitoring the biosensor performance using nanometer-thick doped NiO film electrodes. Obtained results demonstrated the potential of ultrasonic spray deposition method for the massproduction of high-performance nonenzymatic nanometer-thick film biosensors.

This article focuses biosensors based on the electrohydrodynamic jet printing processes, including the fabrication process, micro/nano‐material characteristics, and the sensing principle. Electrohydrodynamic jet printing provides a novel way to fabricate micro/nano‐structures for flexible/wearable biosensors with excellent characteristics of low detection limits, high sensitivities, and fast responses. The nonwoven nanofibrous mats have been used as support substrates, detection elements, and sensor electrodes to enhance the sampling, reaction, and detection in the biosensing processes. Large‐scale electrospinning techniques are discussed to efficiently produce nanofibers for the industrial nanofiber applications. The near‐field electrospinning technique is also introduced which can overcome the bending instability in the nanofiber deposition process to make orderly nanofibrous patterns as the sacrificial structure for the fabrication of microfluidic chips as bioreactor chambers. The functional nanofibers increase the biosensing interfaces and sensing sensitivity with good flexibility to realize applications such as the vital signs detection for the fields of disease diagnosing, infection control, and health care. With these great advantages, electrohydrodynamic jet printing provides new opportunities for the development of point of care medical.
