“…Various hybrid nanomaterials films such as TiO 2 /MWNTs [23], Au NPs/CNTs [24,25], and MWNTsFc [26] have been used to immobilize proteins or enzymes on electrode surface for either mechanistic study of the proteins or fabricating electrochemical biosensors. These hybrid nanomaterials exhibited desirable microenvironment for protein immobilization and great facilitation of the electron transfer compared with those of the individual components [27,28].…”

A novel matrix, multiwalled carbon nanotubes supported nickel oxide nanoparticles composite nanomaterial (NiO@MWNTs), for immobilization of protein and biosensing was designed using a simple and effective hydrothermal method. Using myoglobin (Mb) as a model, the direct electrochemistry of immobilized Mb indicated the matrix could accelerate the electron transfer between protein's active sites and the electrode. The modified electrode shows excellent electrocatalytic activity toward the reduction of H 2 O 2 without the help of an electron mediator. The simple operation, fast response, acceptable stability, and reproducibility of the proposed biosensor indicated its promising application in protein immobilization and preparation of the third generation biosensors.

“…In the literatures reported, the covalent method is a more effective way to stabilize the mediators on the electrode. For example, the mediators were linked on the MWCNTs (Qiu et al, 2009), the polymer matrix (Himuro et al, 2009) or even the enzyme directly (Wu et al, 2008). Moreover, the mediator was linked with the electrode and the redox center of enzyme for increasing the efficiency of electron transfer from enzymes to the external circuit through mediators (Zayats et al, 2008).…”

“…This is reduced by the GOx reaction and transfers its electrons to the electrode. In this sense, an approach is to modify the nanotubes with an electrochemical mediator such as ferrocene, 50 ferricyanide, 51 or another. A further improvement in sensor performance is made possible by the combination of CNTs with various nanoparticles, for example, noble metals (silver, gold, platinum) or silica, titanium dioxide, and others (Figure 2, right).…”

Nowadays nanotechnology has many applications in products used in various areas of daily life; however, this technology has also an option in modern medicine and pharmacy. Therefore, this technology is also an attractive option for the field of diagnosis and treatment of diabetes. Many people with diabetes measure their blood glucose levels regularly to determine the insulin dose. Ideally glucose values would be measured noninvasively (NI). However, none of all the NI approaches studied in the past decades enabled reliable NI measurements under all daily life conditions. Particularly an unfavorable signal-to-noise ratio turned out to be problematic. Based on the known physical possibilities for NI glucose monitoring the focus of this review is on nanotechnology approaches. Functional prototypes exist for some of these that showed promising results under defined laboratory conditions, indicating a good sensitivity and selectivity for glucose. On the second hand is to optimize the technological process of manufacturing. In view of the rapid progress in micro-and nanoelectronics hopefully NI glucose monitoring systems can be developed in the near future.
