“…The previous paragraph explains the SPR biosensor that uses a prism to implement it. Other coupling methods that can be used as alternatives include gratings [ 39 , 40 ], waveguide [ 41 , 42 ], and optical fiber [ 43 , 44 ]. The basic differences between these four coupling methods are shown in Figure 3 .…”

The development of sensitive and specific exosome detection tools is essential because they are believed to provide specific information that is important for early detection, screening, diagnosis, and monitoring of cancer. Among the many detection tools, surface-plasmon resonance (SPR) biosensors are analytical devices that offer advantages in sensitivity and detection speed, thereby making the sample-analysis process faster and more accurate. In addition, the penetration depth of the SPR biosensor, which is <300 nm, is comparable to the size of the exosome, making the SPR biosensor ideal for use in exosome research. On the other hand, another type of nanoplasmonic sensor, namely a localized surface-plasmon resonance (LSPR) biosensor, has a shorter penetration depth of around 6 nm. Structural optimization through the addition of supporting layers and gap control between particles is needed to strengthen the surface-plasmon field. This paper summarizes the progress of the development of SPR and LSPR biosensors for detecting exosomes. Techniques in signal amplification from two sensors will be discussed. There are three main parts to this paper. The first two parts will focus on reviewing the working principles of each sensor and introducing several methods that can be used to isolate exosomes. This article will close by explaining the various sensor systems that have been developed and the optimizations carried out to obtain sensors with better performance. To illustrate the performance improvements in each sensor system discussed, the parameters highlighted include the detection limit, dynamic range, and sensitivity.

“…[1][2][3][4] First introduced as biosensor by Nylander and Liedberg in 1982, 5 SPR biosensors have been developed in various configurations such as coupled with prism, grating, and fiber optics. 6,7 To date, this device is not only used for medical applications such as detecting glucose, 8 DNA, 9 exosomes, 10 antigen, 11 virus, 12 but has also been used in the field of food safety, 13,14 and environmental monitoring. 15 Although SPR biosensors have long been explored, this device still relies on gold as a transducer material, making cheap devices challenging to achieve.…”

2D materials such as graphene and MoS2 have a crucial role in improving the performance of optical sensors. In this work, we investigated a lossy mode resonance (LMR) sensor composed of MgF2 and 2D materials. The transfer matrix method has been chosen to determine the reflectance curve of the sensor with different thicknesses of MgF2 and 2D materials. The computational results show that the LMR sensor generated with s-polarized light has a better resonance. The existence of exciton in MoS2 also has a very dominant contribution to the resulting resonance. There are two absorption peaks around the wavelengths of 610 and 652 nm which are caused by the presence of excitons A and B in MoS2. When graphene- and MoS2-based chips are compared, MoS2-based chips display a wider detection range with better signal stability. A sensitivity of 70.37°/RIU can be achieved with MgF2 (200 nm)/MoS2 (5 layers). In addition, the proposed LMR sensor has a penetration depth that is two times higher than conventional SPR sensors, making it possible to replace SPR sensors which rely heavily on gold as their transducer.
