“…Another interesting work is that of Unal et al [ 109 ]. They developed an amperometric EFB based on organoclay nanofibers, consisting of poly(vinyl)alcohol (PVA) and polyamidoamine (PAMAM) dendrimers intercalated within a montmorillonite clay to detect glucose in soft drinks, Figure 5 .…”

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.

“…Various research groups have studied the role of different types of modication methods (Table 6) in sensor detection, and whether they have achieved good detection results. Unal et al 141 modied organoclaymontmorillonite (Mt) with PAMAM generation-2 (PAMAMG2) dendrimers, and PVA/PAMAM-Mt nanobers were prepared by electrospinning with PVA as the polymer matrix. Glucopyranose oxidase was immobilized on the surface of the nanober-modied electrode to obtain the biosensor.…”

“…Fibrous materials, so often used in industrial applications and the textile industry, have now migrated into biomedical research. To date, polymer-based fibers with diameters on the micro- or nanoscale have been explored in drug delivery [ 1 , 2 , 3 , 4 ], wound healing [ 5 , 6 , 7 ], tissue engineering [ 8 , 9 , 10 ], and biosensor technologies [ 11 , 12 , 13 ] due to their high surface-area-to-volume ratio, mechanical strength, porosity, potential for surface modification, and tunability [ 13 , 14 , 15 ]. Equally important in biomaterials engineering, however, is the need for materials to be both biocompatible and biodegradable.…”

Fibrous materials have garnered much interest in the field of biomedical engineering due to their high surface-area-to-volume ratio, porosity, and tunability. Specifically, in the field of tissue engineering, fiber meshes have been used to create biomimetic nanostructures that allow for cell attachment, migration, and proliferation, to promote tissue regeneration and wound healing, as well as controllable drug delivery. In addition to the properties of conventional, synthetic polymer fibers, fibers made from natural polymers, such as proteins, can exhibit enhanced biocompatibility, bioactivity, and biodegradability. Of these proteins, keratin, collagen, silk, elastin, zein, and soy are some the most common used in fiber fabrication. The specific capabilities of these materials have been shown to vary based on their physical properties, as well as their fabrication method. To date, such fabrication methods include electrospinning, wet/dry jet spinning, dry spinning, centrifugal spinning, solution blowing, self-assembly, phase separation, and drawing. This review serves to provide a basic knowledge of these commonly utilized proteins and methods, as well as the fabricated fibers’ applications in biomedical research.
