“…For example, previous studies used smartphone-assisted Sensit Smart potentiostat, the smallest ready-to-go potentiostat to perform electrochemical detection. [84,[185][186][187] Another interesting example of the portable potentiostat is based on near-field communication (NFC) technology. [188,189] NFC is a wireless communication technology that allows two compatible devices to establish contactless connections.…”

DNA chips play a crucial role in point‐of‐care diagnostics by enabling rapid and accurate detection of genetic information. These chips offer high sensitivity and selectivity, allowing for the identification of specific DNA sequences associated with diseases and pathogens. Integration into lab‐on‐chip platforms streamlines and miniaturizes diagnostic workflows, paving the way for cost‐effective, portable, and user‐friendly testing devices that can revolutionize healthcare delivery. In this review, a comprehensive description of the platforms utilized in DNA analysis, including microfluidic devices and integrated DNA chips, is provided. It explores the selection and immobilization of DNA probes for improved selectivity. Additionally, it covers diverse detection techniques such as optical detection (colorimetry and fluorescence) and electrochemical techniques. In these discussions, it is aimed to provide a thorough understanding of the current state of the art in DNA biosensor‐integrated lab‐on‐chip technology for point‐of‐care testing. The continued advancements in DNA chip technology hold immense promise for the development of next‐generation point‐of‐care diagnostics, where integrated sample preparation and rapid results generation can further enhance patient outcomes and contribute to the effective management of diseases.

“…Chailapakul et al reported that single-walled CNTs with Pt nanoparticles deposited on them could be used as substrates for antibodies' immobilization on an electrode surface, thus boosting the electrochemical sensitivity. It was used to modify paper-based, screen-printed graphene electrodes (SPGE) for the detection of HCVcAg through sensitive, disposable, and inexpensive means, which showed satisfactory results when applied in clinical samples [44]. However, the modified electrode cannot be reused and multiple steps immobilizing the antibody are necessary to achieve high-specificity detection.…”

Viral hepatitis is a global health concern mostly caused by hepatitis B virus (HBV) and hepatitis C virus (HCV). The late diagnosis and delayed treatment of HBV and HCV infections can cause irreversible liver damage and the occurrence of cirrhosis and hepatocellular carcinoma. Detecting the presence and activity of HBV and HCV is the cornerstone of the diagnosis and management of related diseases. However, the traditional method shows limitations. The utilization of nanomaterials has been of great significance in the advancement of virus detection technologies due to their unique mechanical, electrical, and optical properties. Here, we categorized and illustrated the novel approaches used for the diagnosis of HBV and HCV.

“…Using a peptide nucleic acid-functionalized SWCNT-FET biosensor, Dastagir et al [ 59 ] also exhibited the explicit and label-free detection of a hepatitis C virus RNA sequence, with a detection limit of 0.5 pM. The deposition precipitation approach was used by Pusomjit et al [ 60 ] to create Pt nanoparticles that were later coated onto SWCNTs. The generated nanocomposite was finally used as a substrate to immobilize antibodies on a paper-based, SP graphene electrode surface for the purposes of analyzing the hepatitis C virus.…”

It has been proven that viral infections pose a serious hazard to humans and also affect social health, including morbidity and mental suffering, as illustrated by the COVID-19 pandemic. The early detection and isolation of virally infected people are, thus, required to control the spread of viruses. Due to the outstanding and unparalleled properties of nanomaterials, numerous biosensors were developed for the early detection of viral diseases via sensitive, minimally invasive, and simple procedures. To that aim, viral detection technologies based on carbon nanotubes (CNTs) are being developed as viable alternatives to existing diagnostic approaches. This article summarizes the advancements in CNT-based biosensors since the last decade in the detection of different human viruses, namely, SARS-CoV-2, dengue, influenza, human immunodeficiency virus (HIV), and hepatitis. Finally, the shortcomings and benefits of CNT-based biosensors for the detection of viruses are outlined and discussed.
