“…The implementation of some optical phenomena for biosensing such as SPR (Nootchanat et al, 2019;Zhao et al, 2019), SERS (Langer et al, 2020;Liu et al, 2020), and light interference (Chen et al, 2019;J. Wang et al, 2020) became the seed of a high scientific activity in the last decades, which have provided a great knowledge on innovative, sensitive and label-free bioanalytical systems.…”

“…Surface plasmon resonance is a practical and label-free optical sensing technology based on the differential refractive index changes of the molecular surface. In essence, SPR is generated from the resultant force of free charge oscillations and electromagnetic waves at the interface of the medium and metal (Zhao et al, 2019). Thus far, SPR biosensors have been employed in the fields of food (food allergens and mycotoxins), medicine (biomarkers and genes), and so on (Breveglieri et al, 2019;Jena et al, 2019;Wei et al, 2019;Zhou et al, 2019).…”

Aspergillus exists commonly in many crops and any process of crop growth, harvest, storage, and processing can be polluted by this fungus. Once it forms a biofilm, Aspergillus can produce many toxins, such as aflatoxin B1 (AFB1), ochratoxin, zearalenone, fumonisin, and patulin. Among these toxins, AFB1 possesses the highest toxicity and is labeled as a group I carcinogen in humans and animals. Consequently, the proper control of AFB1 produced from biofilms in food and feed has long been recognized. Moreover, many biosensors have been applied to monitor AFB1 in biofilms in food. Additionally, in recent years, novel molecular recognition elements and transducer elements have been introduced for the detection of AFB1. This review presents an outline of recent progress made in the development of biosensors capable of determining AFB1 in biofilms, such as aptasensors, immunosensors, and molecularly imprinted polymer (MIP) biosensors. In addition, the current feasibility, shortcomings, and future challenges of AFB1 determination and analysis are addressed.

“…Compared to the prism coupling based SPR sensor, optical fiber has the advantages of easy fabrication and possibility of miniaturization that is very useful for remote sensing. However, the molecular kinetics of the analyte-ligand interaction cannot be determined using fiber-optic sensing and can only be executed using prism-based SPR sensing [43]. Moreover, optical fiber sensing has its own challenges such as easy breakage of single mode fiber (SMF) when bent in order to increase detection sensitivity as well as difficulty in coating multiple layers on the thin fiber.…”

This paper reviews Kretschmann-based SPR sensor utilizing ZnO thin films and nanostructures for performance enhancement. The advancement in surface plasmon resonance technology relies on low-cost, high sensitivity and high selectivity sensor. Metal oxide has been incorporated in SPR sensor to be used for detection of biological and chemical compounds. ZnO as one of the metal oxides is an attractive material due to its unique physical and optical properties. Numerous techniques for fabrication and characterization of ZnO on SPR gold substrate have been studied. The mechanism for gas and biomolecules detection depends on their interaction with ZnO surface, which is mainly attributed to the high isoelectric point of ZnO. There are several types of ZnO nanostructures which have been employed for SPR application based on the Kretschmann configuration. In future, the thin film and nanostructures of ZnO have potential applications for miniature design, robust, high sensitivity, and low-cost portable type of SPR biosensor to be used for on-site testing in real-time and label-free manner.
