“…Also, to improve the sensing performance of the sensor, its structural parameters are studied in detail. The results show that in our proposed glucose biosensor, the sensitivity is as high as S = 677 nm RIU −1 , which is higher than the reported value in [28].…”

In this study, a new plasmonic biosensor is proposed, which is highly sensitive with a compact structure, based on numerical methods for glucose concentration monitoring in different samples. The biosensor is based on a metal-insulator-metal waveguide and a ring resonator, and the calculated results are analyzed. The glucose biosensor operation is based on the refractive index of the glucose solution in the structure. In this study, to improve the sensitivity of the biosensor, the effect of the inner radius size parameter on spectral sensing has been fully analyzed. This biosensor in resonance wavelengths has a linear relationship with the refractive index of the glucose solution. In this structure, the maximum linear sensitivity is in glucose concentration. In addition, compared to other similar sensors, this biosensor has a label-free detection basis and has a very simple and ultra-compact structure: its size is . Considering the special features of this sensor, it could be used as optical on-chip biosensors for glucose concentration monitoring.

In this paper, a compact and highly sensitive refractive index plasmonic sensor, based on a metal-insulator-metal (MIM) waveguide coupled to double hexagonal ring-shaped resonators in the mid-infrared range, is proposed and analyzed using the finite-difference time-domain (FDTD) method embedded in the commercial simulator R-soft, where it has been found that the transmission peaks and dips positions can be easily manipulated, by simply adjusting the structural parameters of the proposed design, such as the inner side length and the distance between the centers of the two hexagonal ring resonators. So, these parameters have a key role in the sensor's performances, and it is clearly noticed from the results, where a linear link between the refractive index of the material under testing and its wavelength resonances was established. Furthermore, the maximum achievable linear sensitivity was S = 4074 nm/RIU, with a matching sensing resolution of 2.45 × 10 −6 RIU; the temperature sensitivity is around 1.55 nm/ • C; and the highest linear sensitivity is S = 3910 nm/RIU in 0-200 g/L glucose concentration, making this proposed sensor an attractive one, to be implemented in high-performance nano and bio-sensing devices.

“…Mohammad presented and discussed the design of a surface plasmon photonic glass fiber (PCF) biosensor for glucose monitoring. The numerical results show that the D-shaped plasmonic PCF after etching three rows of air holes and using gold as a doping structure can reach a sensitivity of 200 nm/RIU [91].…”

Fiber Optic Sensors: A Review for Glucose Measurement

et al. 2021

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.
