In this study, a low‐cost, disposable, sensitive and selective electrochemical sensor was developed for glucose determination, which is based on a pencil graphite electrode (PGE) modified with nickel hydroxide. Cyclic voltammetry was used to deposit nickel on PGE. The morphology and composition of the unmodified and modified PGE electrodes were characterized by field‐emission scanning electron microscopy (FE‐SEM), atomic force microscopy (AFM) and energy‐dispersive X‐ray spectroscopy (EDX). The performance of the as modified electrode towards the electrooxidation of glucose in alkaline media was evaluated with cyclic voltammetry and amperometry techniques. A linear relationship between the concentration of glucose and oxidation peak currents was observed in two concentration ranges of 0.004–3.5 mM and 3.5–9.0 mM. The detection limit was 2 μM at signal‐to‐noise ratio of 3. In addition to a fast response time (<2 s), the proposed sensor preserved 93 % of its original response towards glucose after 28 days. Also, the sensor showed a good reproducibility and high selectivity for glucose oxidation in the presence of common interfering species. The use of Ni(OH)2/PGE sensor was successfully tested in the determination of glucose in human blood serum for the first time in the literature.

Hydroxyapatite nanoparticles (HaNP) modified pencil graphite electrodes (PGEs) were developed for the first time in the literature, and accordingly they were applied for electrochemical monitoring of sequenceselective DNA hybridization. The experimental conditions for HaNP modification of PGE, and DNA hybridization related to Hepatitis B Virus (HBV) DNA sequence were optimized. The microscopic and electrochemical characterization of HaNP-PGE in contrast to the unmodified one was utilized. Under optimized experimental conditions, the selectivity of HBV DNA probe immobilized biosensor was tested against to non-complementary (NC), mismatch (MM) sequences and the mixture of target:NC (1 : 1) or target: MM (1 : 1).

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.
