Graphene-Fiber Biochemical Sensors: Principles, Implementations, and Advances

Abstract

Single atomically thick graphene, with unique structural flexibility, surface sensitivity, and effective light-mater interaction, has shown exceptional advances in optoelectronics. It opens a door for diverse functionalized photonic devices, ranging from passive polarizers to active lasers and parametric oscillators. Among them, graphene-fiber biochemical sensors combine the merits of both graphene and fiber structures, demonstrating impressively high performances, such as single-molecule detectability and fast responsibility. These graphene-fiber biochemical sensors can offer tools in various applications, such as gas tracing, chemical analysis, and medical testing. In this paper, we review the emerging graphene-fiber biochemical sensors comprehensively, including the sensing principles, device fabrications, systematic implementations, and advanced applications. Finally, we summarize the state-of-the-art graphene-fiber biochemical sensors and put forward our outlooks on the development in the future.

Hybrid structure of u bent optical fiber local surface plasmon resonance sensor based on graphene

“…In comparison to traditional SPR sensors without 2D materials, SPR sensors with 2D materials are more sensitive [17]. Graphene, as a pioneer of two-dimensional materials, has made significant discoveries in fields such as materials science, biology, and medicine to apply physics, chemistry, and electronics as a result of its linear band structure and thickness of an atom [18]. In the previous studies like [5], [16], [19] the U shape LSPR sensor designed by removed the cladding of optical fiber by acetone to expose the core without removing any part from the core.…”

Wet Spinning of Graphene Oxide Fibers with Different MnO2 Additives

“…Graphene fibers (GFs) present exceptional mechanical, thermal, and electrical properties due to densely stacked graphitic sheets and less grain boundaries among sp 2 -carbon clusters in comparison with conventional carbon fibers (CFs) manufactured from pyrolysis of PAN, cellulose, or pitch-based precursors. , Due to these exceptional properties, extensive research has been conducted to fabricate GFs to attain maximum performances with minimum production costs. , Apart from manufacturing perspectives, GFs and their derivatives have been applied in various research areas such as composites, sensors, , and energy storage systems. − Improvement of physical properties and creation of additional functions in GFs can be achieved via incorporation of various additives in the GFs. For instance, fabrication of reduced graphene oxide (rGO)/silver nanowires composite fibers significantly improved electrical conductivity and mechanical strength of the composite fibers .…”

Recent Advances in Polymer-Based Biosensors for Food Safety Detection

“…The principle of optical biosensors is based on the detection and analysis of changes in light signals resulting from the interaction between a biological recognition element and a target analyte. These biosensors utilize the properties of light, such as absorption, reflection, fluorescence, or refraction, to quantitatively or qualitatively measure the presence and concentration of specific analytes [ 16 , 17 ].…”
