“…Since the production of the first paper-based device attributed to Müller and Clegg [47] and the production of paper-based microfluidics by the Whitesides group, which was the first device for determination of glucose created through a photolithography technique [51], there have been a lot of developments in fabrication techniques and paper-based applications [52]. Generally, the fundamental techniques of PADs fabrication are photolithography [53], wax printing [54,55], inkjet [56], screen printing [57], laser treatment [58], and wet etching [59]. Of course, the fabrication techniques of PADs are similar to those of microfluidic PADs; they are based on the creation of hydrophilic zones for electrochemical detection with hydrophobic borders on paper to confine the flow of fluid inside the desired position.…”

Personalized health care (PHC) includes personalized, preventive, predictive and participatory approaches that are significant in new diagnostics. This personal health care requires fast, accurate and minimally invasive diagnostic tools that make it possible to evaluate and monitor the process of disease by diagnosing specific disease biomarkers. Point-of-care testing (POCT) involves a wide range of diagnostic tools that meet this purpose. Electrochemical paper-based devices (ePADs) have been introduced as simple, inexpensive, portable and disposable measurement devices to be used in many POCT applications, especially in handling emergencies and outpatient as well as remote usages. Electrochemical detection is a real quantitative detection method with better sensitivity, selectivity and detection limits than indirect measurement methods. In recent years, there has been a revolution in quantitative detections by POCT, thanks to the benefits of electrochemical sensors and paper substrates. In this paper, recent developments in ePADs, focusing on the properties of paper, reasons for its use in the devices, techniques of device and electrode fabrications, and their application particularly in clinical diagnosis, are reviewed.

Paper-based analytical devices (PADs) and Electrospun Fiber-Based Biosensors (EFBs) have aroused the interest of the academy and industry due to their affordability, sensitivity, ease of use, robustness, being equipment-free, and deliverability to end-users. These features make them suitable to face the need for point-of-care (POC) diagnostics, monitoring, environmental, and quality food control applications. Our work introduces new and experienced researchers in the field to a practical guide for fibrous-based biosensors fabrication with insight into the chemical and physical interaction of fibrous materials with a wide variety of materials for functionalization and biofunctionalization purposes. This research also allows readers to compare classical and novel materials, fabrication techniques, immobilization methods, signal transduction, and readout. Moreover, the examined classical and alternative mathematical models provide a powerful tool for bioanalytical device designing for the multiple steps required in biosensing platforms. Finally, we aimed this research to comprise the current state of PADs and EFBs research and their future direction to offer the reader a full insight on this topic.

The present study reports the fabrication of reduced graphene oxide (rGO)/gold nanoparticles (AuNP) nanocomposites modified cellulose fiber paper-based electrochemical biosensor for procalcitonin (PCT) biomarker detection. PCT is a biomarker specific for bacterial infection (BI) detection and has gained much attention as a potential solution to the problems associated with determining appropriate antibiotic use. In sepsis and other severe infections, serum PCT levels increase to values above 100 ng mL À 1 in response to pro-inflammatory stimulation. The structural and morphological characterization of the rGO-AuNP composite are investigated using UV-Vis spectroscopy, FTIR spectroscopy, X-ray diffraction, and scanning electron microscopy. Monoclonal antibodies specific to PCT were covalently immobilized onto the rGO-AuNP nanocomposite modified paper to fabricate an electrochemical biosensor. The fabricated biosensor exhibits linearity in the PCT concentration range 10 À 15 × 10 3 pg mL À 1 , with a low detection limit 10 pg mL À 1 . Furthermore, the proposed biosensor also exhibited good selectivity and could detect PCT biomarkers even in the presence of other interfering electroactive species such as glucose, oxalic acid, and urea. The proposed CF-based biosensor has been proven as an accelerated simple point-ofcare (POC) exploratory approach for early PCT diagnosis in inadequate areas with limited production facilities, computational techniques, and highly skilled experts.
