A facile and green electrochemical method for the fabrication of three‐dimensional porous nitrogen‐doped graphene (3DNG) modified electrode was reported. This method embraces two consecutive steps: First, 3D graphene/polypyrrole (ERGO/PPy) composite was prepared by electrochemical co‐deposition of graphene and polypyrrole on a gold foil. Subsequently, the ERGO/PPy composite modified gold electrode was annealed at high temperature. Thus 3DNG modified electrode was obtained. Scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS) and Raman spectroscopy were used to characterize the structure and morphology of the electrode. The electrode exhibits excellent electroanalytical performance for the reduction of hydrogen peroxide (H2O2). By linear sweep voltammetric measurement, the cathodic peak current was linearly proportional to H2O2 concentration in the range from 0.6 μM to 2.1 mM with a sensitivity of 1.0 μA μM−1 cm−2. The detection limit was ascertained to be 0.3 μM. The anti‐interference ability, reproducibility and stability of the electrode were carried out and the electrode was applied to the detection of H2O2 in serum sample with recoveries from 98.4 % to 103.2 %.

“…The optical parameters for H 2 O 2 sensing materials are summarized in Table 1. Extensive studies have been reported on absorbance-based [23][24][25][26][27] and fluorescence-based [28][29][30][31][32] H 2 O 2 sensing method. The currently available optical sensing methods utilized the changes in absorbance or luminescence intensity as detecting signal.…”

In this paper, the multicolor photoluminescence carbon quantum dots (CQDs) have been synthesized by one step hydrothermal method to analyze hydrogen peroxide (H 2 O 2 ). These CQDs exhibited multicolor emission under a single wavelength excitation for the quantification of H 2 O 2 . Using an LED with a central wavelength of 365 nm as the excitation source, it is shown that the red emission CQDs capable of detecting H 2 O 2 over the linear range of 0-88.2 mM and the H 2 O 2 sensitivity of wavelength shift to changes in the H 2 O 2 concentration was found to be 0.18 nm/mM. These results of the optical sensing method can be used in practice detection of H 2 O 2 and could offer a new approach for developing a new biosensor. The CQDs exhibit good emission property and high stability, as well as excitation-independent emission behavior. Moreover, it is attractive that CQDs can be used as an effective fluorescent probe for the detection of H 2 O 2 with linear Stern-Volmer plot and wavelength shift in an aqueous solution.

This work comprehends a review of nanostructured materials employed in the fabrication of optical fiber sensors in the last years. The continuous advances in nanofabrication techniques have enabled to manipulate the matter precisely producing well defined nanostructurated coatings or repetitive patterns at nanoscale level. The interactions of light with these nano-organized materials or patterns at the nanoscale level enable to observe interesting phenomena, such as interferometry, fluorescence, absorbance, resonances and many others which can be exploited in the fabrication of sensing devices. A particular case consists of optical fiber sensors, where the light travelling through an optical fiber interacts with the sensitive layer. The properties of the sensitive layer, such as the organization, physical properties, chemical bounds etc. will determine the sensing characteristics of the final device. The utilization of some of the most common nanostructured materials, such as polymers, nanoparticles, metals, metal oxides or biological coatings are reviewed here.
