“…Depending of the carbon source (e.g. graphite, CNT, SiC, agricultural waste) and synthesis method, various graphene forms with distinct qualities can be obtained, such as multilayer (ML) graphene [44, 45], graphene nanoribbons after unzipping the CNTs [46], graphene oxide, reduced graphene oxide (rGO) and graphene quantum dots (GQDs) [47]; plus functionalized graphene with various additional groups (COOH, NH 2 , etc.) [48, 49].…”

Diverse properties of graphenic materials have been extensively explored to determine properties that make good electrochemical nanomaterial-based biosensors. These are reviewed by critically examining the influence of graphene nano-morphology, lattice defects and conductivity. Stability, reproducibility and fabrication are discussed together with sensitivity and selectivity. We provide an outlook on future directions for building efficient electrochemical biosensors.

“…lodged platinum nanoparticles on the surface of MWCNT and casted on GCE for the simultaneous detection of AA, DA, and UA . The binders such as N′,N′‐dimethylphenothiazin‐5‐ium‐3,7‐diamine were used to attach NPs with CNTs to improve the stability . Similarly, La‐MWCNTs nanocomposite electrode was used to detect AA, DA, and UA (Figure ).…”

Electrochemical sensors for selective analysis of biomolecules got tremendous attention due to their better sensitivity and construction possibility of the portable cost‐effective devices. The individual or simultaneous sensing of ascorbic acid (AA), dopamine (DA), and uric acid (UA) is challenging due to their close electrooxidation and co‐existing. Recent years, substantial progress is made to develop electrode with smart materials to overcome the issue related to simultaneous sensing. This review is comparatively consolidating the work was done in fabrication of electrochemical sensors for the simultaneous sensing of AA, DA and UA. The various modification materials such as graphene, CNTs, conductive polymers and the ionic liquids characteristics are concisely described with their figure of merits. In the end, the critical analysis, future prospects, and challenges in commercialization are described.

This work presents a low cost, simple and adequately reliable electrochemical alternative for the determination of uric acid in human serum in comparison to the enzymatic colorimetric reference method. The quality of the electrochemical measurements was assessed by comparing its uncertainty with a target value of 0.56 mg dL-1 and the measurements were carried out by the standard addition method. The modified working electrode consists of 25% lignin, 60% nanocarbon, 15% mineral oil and electrodeposited metallic copper. The uncertainty of measurement was estimated by the bottom-up approach, from which uncertainty components were combined by applying the uncertainty propagation law (LPI), the numerical method of Kragten and the Monte Carlo Simulation Method (MCM). The analytical procedure was successfully applied in the analysis of physiological sera added at 1.0, 3.0, 5.0, 7.0 and 9.0 mg dL-1 of AU and for two other samples of human saline. The results of the measurements carried out for the different serum samples using the proposed method, associated to the different methods for estimating the uncertainty, showed sufficiently low and metrologically equivalent values, in which the results were shown to be compatible with the estimated reference values.
