An ascorbic acid (AA) electrochemical sensor was fabricated by ferrocene methanol (FcÀ OH) modified multi-walled carbon nanotube yarn (CNTY). The prepared sensor (FcÀ OH/CNTY) exhibited outstanding flexibility, highly stretchability, excellent bendability and obviously electrocatalytic activity for oxidation of ascorbic acid. The morphology of FcÀ OH/CNTY was evaluated by scanning electron microscope. The electrochemical behaviour of FcÀ OH/CNTY sensor was studied by cyclic voltammetry and amperometry measurements. Moreover, the influence of FcÀ OH concentration, applied potential and electrolyte solution pH were also investigated to obtain the best sensor performance. The prepared sensor exhibited a wide linear range from 3 μM to 3.0 mM toward AA, and a detection limit of 1.32 μM (S/N = 3). It also possessed a good lifetime and a fast response speed (2.83 s). In addition, the FcÀ OH/CNTY sensor remained 90 % and 60 % of its initial activity after 100 and 500 times bending, respectively, which indicated a potential application on flexible, implantable and/or wearable electrochemical sensors.

“…Matysiak-Brynda et al [112] used Fc to modify rGO and built a glucose sensor, in which Fc facilitated the electron exchange between glucose oxidase (GOx) and the electrode surface. The schemes for the synthesis of two proposed biosensors, one with an aldehyde substitute (rGOÀ Fc) and the other with a carboxylic acid substitute (rGOÀ Fc(COOH) 2 ), are presented in Figures 6 (A) and (B), respectively.…”

Owing to their versatility and unique characteristics, graphene‐based materials have been used extensively for the development of electrochemical sensors and biosensors. The key to the maximum potential of these materials is the understanding of the role their structure plays in their modification processes. Herein, we summarize some structural characteristics of graphene oxide (GO) and reduced graphene oxide (rGO) and explore different surface modification methods for electrochemical sensing applications. surveyed the most recent applications of these materials as (bio)sensors, particularly for environmental monitoring and health‐related applications, such as quantification of biomarkers and metabolites and detection of cancer cells. The low detection limits, selectivity toward target molecules, and robustness of GO‐ and rGO‐based electrodes render them critical materials for the preparation of sensors for routine analysis and monitoring.

“…Using portable electronic devices to directly detect glucose is a convenient diagnostic method in the initial steps. A literature survey found that glucose sensors can be divided into two categories: enzyme-based sensors [ 5 , 6 ] and enzyme-free sensors [ 7 , 8 ]. Enzyme-based electrochemical biosensors are complex, expensive and affected by temperature and pH due to enzyme activity.…”

Herein, a composite structure, consisting of Cu nanoparticles (NPs) deposited onto carbon nanotubes and modified with ferrocene-branched chitosan, was prepared in order to develop a nonenzymatic electrochemical glucose biosensor ferrocene-chitosan/carbon nanotube@ Cu (Fc-CHIT/CNT@Cu). The elemental composition of the carbon nanohybrids, morphology and structure were characterized by various techniques. Electrochemical impedance spectroscopy (EIS) was used to study the interfacial properties of the electrodes. Cyclic voltammetry (CV) and chronoamperometry methods in alkaline solution were used to determine glucose biosensing properties. The synergy effect of Cu NPs and Fc on current responses of the developed electrode resulted in good glucose sensitivity, including broad linear detection between 0.2 mM and 22 mM, a low detection limit of 13.52 μM and sensitivity of 1.256 μA mM−1cm−2. Moreover, the modified electrode possessed long-term stability and good selectivity in the presence of ascorbic acid, dopamine and uric acid. The results indicated that this inexpensive electrode had potential application for non-enzymatic electrochemical glucose detection.
