“…This observation indicates that not only the metal nanoparticles but also the narrow gaps between them are all covered by a layer of graphene. Since graphene has excellent affinity toward most organic molecules, the graphene layer on nanoparticles and narrow gaps are expected to stabilize enhanced Raman signals [32].…”

“…In 2015 Qiu designed a plastic fiber optic sensor, with a light source, polarization device, reaction zone, spectrometer (USB2000+ miniature fiber optic spectrometer) and a PC. Qui used a LED light source to generate red light of 628 nm wavelength, making measurements on samples of 1-40% glucose concentration [82]. This same year, Verma developed an experimental setup for the characterization of urea and glucose levels (channel 1 and channel 2) shown in Figure 10, having a detection range between 500 to 800 nm with glucose samples on concentrations from 0 to 260 mg/dL.…”

Diabetes mellitus is a chronic metabolic disorder, being globally one of the most deadly diseases. This disease requires continually monitoring of the body’s glucose levels. There are different types of sensors for measuring glucose, most of them invasive to the patient. Fiber optic sensors have been proven to have advantages compared to conventional sensors and they have great potential for various applications, especially in the biomedical area. Compared to other sensors, they are smaller, easy to handle, mostly non-invasive, thus leading to a lower risk of infection, high precision, well correlated and inexpensive. The objective of this review article is to compare different types of fiber optic sensors made with different experimental techniques applied to biomedicine, especially for glucose sensing. Observations are made on the way of elaboration, as well as the advantages and disadvantages that each one could have in real applications.

“…By exploiting the evanescent wave of an optical fiber, carbon allotropes can serve as a functional coating capable of detecting bio-analytes and alter the output light properties for interrogation purposes. For instance, Qiu et al [220] synthesized graphene film using the CVD technique and transferred directly onto the tapered PMMA core section of the plastic optical fiber. The graphene layer serves as a good molecule enricher or an absorbable film supported by the plastic fiber that can firmly absorb glucose molecules onto its surface and alters the output light intensity.…”

Recently, carbon allotropes have received tremendous research interest and paved a new avenue for optical fiber sensing technology. Carbon allotropes exhibit unique sensing properties such as large surface to volume ratios, biocompatibility, and they can serve as molecule enrichers. Meanwhile, optical fibers possess a high degree of surface modification versatility that enables the incorporation of carbon allotropes as the functional coating for a wide range of detection tasks. Moreover, the combination of carbon allotropes and optical fibers also yields high sensitivity and specificity to monitor target molecules in the vicinity of the nanocoating surface. In this review, the development of carbon allotropes-based optical fiber sensors is studied. The first section provides an overview of four different types of carbon allotropes, including carbon nanotubes, carbon dots, graphene, and nanodiamonds. The second section discusses the synthesis approaches used to prepare these carbon allotropes, followed by some deposition techniques to functionalize the surface of the optical fiber, and the associated sensing mechanisms. Numerous applications that have benefitted from carbon allotrope-based optical fiber sensors such as temperature, strain, volatile organic compounds and biosensing applications are reviewed and summarized. Finally, a concluding section highlighting the technological deficiencies, challenges, and suggestions to overcome them is presented.2 of 43 of target molecules or physical parameters. In some instances, surface-modified carbon allotropes also permit multi-parameter detection capabilities of carbon allotrope-based OFS [7]. As such, an insight into the recent advances of carbon allotrope-based OFS can serve as a guideline to develop an effective detection approach for emerging real-world applications. Many review articles on carbon allotrope-based OFS mainly focus on a single type of carbon allotrope and the fundamental theory of carbon allotrope-based OFS [8,9]. Thus, this comprehensive review article encompasses the properties, preparation, sensing mechanisms, nanocoating deposition techniques, physical and biochemical sensing applications. This review aims to highlight the recent research work on carbon allotrope-based OFS that will serve as a reference guide for researchers to develop optimal detection approaches for physical parameters or trace level monitoring of chemical and biomolecules. Four groups of carbon allotropes, including carbon nanotubes (CNT), carbon dots (CDs), graphene, and nanodiamonds (NDs), will be studied. Commonly adopted synthesis approaches, classification of various deposition techniques for the integration of carbon allotropes as the thin film coating of OFS as well as numerous examples of these carbon allotrope-based OFS will also be outlined.
