“…PEI is a conductive polymer that has a density of reactive amine groups which can react with oxygen-rich groups such as -OH and -COOH from nanostructured materials such as CNT. [144] Fe 3 O 4 nanoparticles were first hybridized with CNT and then modified with PEI to produce a sensitive electrochemical sensor and to enhance the kinetic and electrocatalytic properties of electron transfer. The prepared PEI/ Fe 3 O 4 NPs/CNTs/GCE composite sensors demonstrated high diagnostic precision and sensitivity in detecting CIP in real samples, such as commercial tablets, serum, and urine biological samples.…”

Quinolone antibiotic is known for its effectiveness in treating infectious disease, and has been used widely for humans and also in animals. Continuous use of antibiotics could promote antibiotic resistance as well as result in the accumulation of antibiotic residues in food. Therefore, monitoring the quinolone antibiotic is important. Meanwhile, carbon‐based electrode is known as a material that has been used widely for electrochemical sensor application. It has been used in its bare form and modified form to improve the electrode catalytic performance. In this review, we summarize the utilization of unmodified and modified carbon‐based electrode in detecting various types of quinolone antibiotics. It is expected to provide comprehensive information on related topics.

“…These interactions result in an electrochemically stable PAZ-encapsulated phosphorene (PEP) nanostructure, which preserves the layered structure of phosphorene while reducing the reactivity of phosphorus atoms with H 2 O and O 2 molecules. [23,24] This encapsulation also prevents the formation of coffee-rings by recirculating phosphorene flakes. The facile chemical synthesis process of PEP is depicted in Figure 1A.…”

Heteroatom-incorporated graphene represents a prominent family of materials utilized as active electrodes for multimodal sensing and energy storage applications. Herein, a novel polyaziridine-encapsulated phosphorene (PEP)incorporated flexible 3D porous graphene (3DPG) electrode is developed using facile, cost-effective laser writing, and drop-casting techniques. Owing to the excellent electrochemical characteristics and surface functionality of the highly stable PEP, the fabricated PEP/3DPG is evaluated as a potential electrode for immunosensing, electrocardiogram (ECG) recording, and microsupercapacitors (MSCs). Under optimized conditions, the produced PEP/3DPG-based carcinoembryonic immunosensor exhibits linear ranges of 0.1-700 pg mL −1 and 1-100 ng mL −1 with a detection limit of 0.34 pg mL −1 and high selectivity. The finger touch-based ECG sensor demonstrates a relatively low and stable impedance at the skin-electrode interface; therefore, the signal-to-noise ratio of the ECG signal received from the fabricated sensor (13.5 dB) is comparable to that of conventional Ag/AgCl electrodes (13.9 dB). Besides, the highest areal capacitance of the prepared MSC reached a magnitude of 16.94 mF cm −2 , which is six times higher than that of a nondoped 3DPG-based MSC. These results demonstrate the effectiveness of the described fabrication procedure and the high utilization potential of the encapsulated phosphorene-doped 3D graphene in multimodal applications.

“…MNMs consist of either elemental magnetic materials such as iron, cobalt, and nickel or their oxides and mixed oxides. Among magnetic iron oxide nanoparticles, magnetite (Fe 3 O 4 ) and maghemite (γ-Fe 2 O 3 ) have attracted the most attention from various fields with regards to their applicability as drug delivery vehicles, − MRI contrast agents, ,, catalysts, − sensors, − and sorbents. ,− MNMs play a key role in immunoassays because these nanoparticles can be surface-modified with antibodies, oligonucleotides, and aptamers to enable selective binding to target viruses or their biomarkers . Functionalized MNMs can be applied in both the separation and detection steps of the immunomagnetic assay process.…”

Magnetic nanomaterials (MNMs) have gained great interest from different fields of study ranging from wastewater treatment to (bio)sensor development, taking advantage of both nanoscale size (allowing high surface-to-volume ratios) and the opportunity for magnetic manipulation. These materials can be surface-modified with antibodies, oligonucleotides, and aptamers to enable selective binding with target viruses or their biomarkers in biological samples. Using an external magnetic field, MNM-virus/biomarker complexes can be effectively isolated for further analysis. In some cases, the role of MNMs is not limited to simply serve as magnetic sorbents for extraction purposes as they have become an active part of some emerging detection processes (e.g., the use of magnetoresistive sensors). The combined application of MNMs with microfluidics for virus detection provides promising avenues for diagnostic tests that are of lower cost, require less time, and have higher specificity and sensitivity over conventional tests. This review focuses on the different approaches of virus detection using MNMs integrated in microfluidic chips. We will discuss recent research findings and provide insights and future perspectives for the development of low-cost and effective COVID-19 diagnostics tests.
