Electrospinning is a simple, low-cost and versatile method for fabricating submicron and nano size fibers. Due to their large surface area, high aspect ratio and porous structure, electrospun nanofibers can be employed in wide range of applications. Biomedical, environmental, protective clothing and sensors are just few. The latter has attracted a great deal of attention, because for biosensor application, nanofibers have several advantages over traditional sensors, including a high surface-to-volume ratio and ease of functionalization. This review provides a short overview of several electrospun nanofibers applications, with an emphasis on biosensor applications. With respect to this area, focus is placed on label-free sensors, pertaining to both recent advances and fundamental research. Here, label-free sensor properties of sensitivity, selectivity, and detection are critically evaluated. Current challenges in this area and prospective future work is also discussed.

There has been limited exploration of carbon nanofiber as a scaffold for cellular attachment and proliferation. In this work, commercially available, pyrolytically stripped carbon nanofiber (cCNF) is deposited over electrospun nanofiber mats, polycaprolactone (PCL) and poly(D-lactide) (PDLA), to immobilize them and investigate whether the 3D cCNF layer's surface augments cell proliferation of human dermal fibroblasts (nHDF). Spectral characterizations, such as XRD and Raman, show that cCNF exhibited crystalline structure with a high graphitization degree.

This study investigates the potential of zinc oxide (ZnO) and Ag-doped zinc oxide (Ag-ZnO) nanoparticles (NPs) (1, 3 and 5 wt%) electrospun into poly(vinylidene fluoride) (PVDF) based triboelectric nanogenerators (TENGs) to harness electrical energy from ambient mechanical vibrations. ZnO and Ag-ZnO NPs were developed using a co-precipitation method. 3 wt% Ag-ZnO doping was optimized to exhibit a higher β-crystalline phase in PVDF (PAZ3).

This study aimed to develop bead-free nanofibers for effective omega-3 encapsulation using optimal mixing ratios of whey protein isolate (WPI)/polyvinyl alcohol (PVA) blends via electrospinning method. Various WPI-PVA ratios (100:0, 90:10, 80:20, 70:30, 60:40, 50:50 v/v) were examined for surface tension, viscosity, and conductivity. SEM images revealed uneven nanofibers with bead at 90:10 and 80:20 ratios, while the 70:30 ratio produced uniform and bead-free nanofibers with an average diameter of 262.

A binder-free and freestanding electrode was designed by uniformly immobilizing carbon quantum dot (CQD)-anchored polyaniline (PANI) heterostructures onto electrospun carbon nanofibers (CNFs) a facile hierarchical assembly process. The fabricated freestanding CNF/PANI/CQD electrode exhibits a unique three-dimensional (3D) network nanostructure, which accelerates ion migration between the interior and surface of the electrode, thereby enhancing its charging and discharging performance. Moreover, the functional groups on the surface of CQDs could anchor PANI through possible chemical bonding, which not only improves the stability of the PANI/CQD heterojunction but also creates an additional conductive channel for the PANI polymer.
