Electrospun one-dimensional (1D) nanostructures are rapidly emerging as key enabling components in gas sensing due to their unique electrical, optical, magnetic, thermal, mechanical and chemical properties. 1D nanostructures have found applications in numerous areas, including healthcare, energy storage, biotechnology, environmental monitoring, and defence/security. Their enhanced specific surface area, superior mechanical properties, nanoporosity and improved surface characteristics (in particular, uniformity and stability) have made them important active materials for gas sensing applications. Such highly sensitive and selective elements can be embedded in sensor nodes for internet-of-things applications or in mobile systems for continuous monitoring of air pollutants and greenhouse gases as well as for monitoring the well-being and health in everyday life. Herein, we review recent developments of gas sensors based on electrospun 1D nanostructures in different sensing platforms, including optical, conductometric and acoustic resonators. After explaining the principle of electrospinning, we classify sensors based on the type of materials used as an active sensing layer, including polymers, metal oxide semiconductors, graphene, and their composites or their functionalized forms. The material properties of these electrospun fibers and their sensing performance toward different analytes are explained in detail and correlated to the benefits and limitations for every approach.

Polydiacetylene (PDA) compound has unique chromatic properties when embedded in methylcellulose base. Therefore, this could be used as intelligent packaging. PDA exhibits blue-to-red color transition under certain stimuli, which was caused by alterations in PDA conjugation length backbone. For a specific color modification, bio-recognition tools were covalently linked with PDA. In this work, a broad-spectrum virulent phage (PVP-SE1) was used as a biorecognition element to detect Salmonella cells due to PDA color change. A series of experiments were performed to monitor colorimetric response. Consequently, chromatic immunoassay could be significant in increasing potential applications of PDA intelligent packaging.

“…In response, exploration into low-cost, portable, real-time sensor development has intensified in recent years [1]. Notably, solid-state sensors based on electrospun polymer nanofibers have gained increasing attention due to their high surface area, mechanical stability, low cost, ease of preparation, and surface functionality [2][3][4].…”

Electrospun nanofibers of a polyaniline (PANi)/ (?)-camphor-10-sulfonic acid (HCSA)/poly(ethylene oxide) (PEO) composite doped with different variants of graphene oxide (GO) were fabricated and evaluated as chemiresistor gas sensors operating at room temperature. A new strategy for enhancing PANi/PEO gas sensor performance is demonstrated using GO dopants reduced via thermal (trGO) or chemical (crGO) routes. By varying the chemical reduction duration (6 h, crGO-6 or 24 h, crGO-24), tunable enhancement of sensor response was achieved. Upon exposure to short-chain aliphatic alcohol vapors, the partially reduced crGO-6 dopant exhibited higher response than GO and crGO-24, suggesting that the dopant enhances sensor performance via increased electrical conductivity over neat GO, and enhanced hydrogen bonding capability over the further-reduced crGO-24 variant. Sensor arrays consisting of PANi/PEO doped with trGO, crGO-6 or crGO-24 moieties successfully identified methanol, ethanol, and 1-propanol vapors using principal component analysis (PCA).
