“…In 2006, Lin analyzed the characteristics of vitamin B 12 and used it as the modification material of the electrode to improve the electrocatalytic activity. The experimental results showed that the electrocatalytic effect of the sensor was good, not only improving the response time but also reducing the maintenance frequency [53]. In 2010, Damos constructed a supramolecular membrane with high stability by using cyclodextrin molecules, which promoted the reduction/oxidation (redox) reaction between the electrodes and dissolved oxygen.…”

Dissolved oxygen is an important index to evaluate water quality, and its concentration is of great significance in industrial production, environmental monitoring, aquaculture, food production, and other fields. As its change is a continuous dynamic process, the dissolved oxygen concentration needs to be accurately measured in real time. In this paper, the principles, main applications, advantages, and disadvantages of iodometric titration, electrochemical detection, and optical detection, which are commonly used dissolved oxygen detection methods, are systematically analyzed and summarized. The detection mechanisms and materials of electrochemical and optical detection methods are examined and reviewed. Because external environmental factors readily cause interferences in dissolved oxygen detection, the traditional detection methods cannot adequately meet the accuracy, real-time, stability, and other measurement requirements; thus, it is urgent to use intelligent methods to make up for these deficiencies. This paper studies the application of intelligent technology in intelligent signal transfer processing, digital signal processing, and the real-time dynamic adaptive compensation and correction of dissolved oxygen sensors. The combined application of optical detection technology, new fluorescence-sensitive materials, and intelligent technology is the focus of future research on dissolved oxygen sensors.

“…Therefore, cobalamin may be immobilized on an electrode surface for oxidation or reduction and electrochemical sensors have been developed using this chemical. [19][20][21] The use of nanomaterials has allowed the development of novel sensors due to their large specific surface areas, excellent conductivity, and high electrocatalytic activity. Carbon nanotubes and graphene nanosheets have been employed for the construction of biosensors.…”

A novel nonenzymatic sensor for the determination of hydrogen peroxide was developed based on a multiwalled carbon nanotube-cobalamin composite using simple electrodeposition. The presence of multiwalled carbon nanotubes in the composite film of the modified glassy carbon electrode mediated the cobalamin redox reaction. The composite modified electrode exhibited good electrocatalytic activity for the determination of hydrogen peroxide by cyclic voltammetry. Linear response of the sensor was obtained for analyte concentrations from 24 to 3120 µM. The sensitivity was approximately 56.5 μA cm −2 μM −1 and the limit of detection was 0.56 μM. The multiwalled carbon nanotube-cobalamin modified sensor provided suitable long-term stability with relatively rapid and reproducible response towards hydrogen peroxide, providing a promising platform for real sample analysis.

“…Therefore, development of DO sensor devices is very important for measuring molecular gaseous oxygen content in environmental water [ 2 ]. Various optical sensors [ 3 – 6 ] and electrochemical sensors [ 7 – 10 ] are investigated for the detection of DO. The optical DO sensors include fluorescent sensors [ 3 , 4 ], electrochemiluminescence sensors [ 5 ] and luminescence sensors [ 6 ].…”

“…This sensor showed low detection limit, good stability and was satisfactorily reproducible, showing potential application in DO and biochemical oxygen demand detection. Three types of electrochemical sensors have been reported for DO detection, amperometric sensors [ 7 , 8 ], galvanic oxygen sensors [ 9 ] and potentiometric sensors [ 10 ]. Martin et al [ 8 ] developed an amperometric sensor for determination of DO by nickel-salen polymeric film modified electrode.…”

This paper investigated two different modification methods of graphene (GN) on ultramicroelectrode array (UMEA) and applied the GN modified UMEA for the determination of dissolved oxygen (DO). The UMEAs were fabricated by Micro Electro-Mechanical System (MEMS) technique and the radius of each ultramicroelectrode is 10 μm. GN-NH2 and GN-COOH were modified on UMEA by using self-assembling method. Compared with GN-NH2 modified UMEA, the GN-COOH modified UMEA showed better electrochemical reduction to DO, owing to better dispersing and more active sites. The GN-COOH on UMEA was electroreduced to reduced GN-COOH (rGN-COOH) to increase the conductivity and the catalysis performance. Finally, the palladium nanoparticles/rGN-COOH composite was incorporated into DO microsensor for the detection of DO.
