Abstract: (170 Views)
In recent decades, the prevalence of human diseases has increased continuously, this has led researchers to design biosensors with new technologies. Research shows that combining two-dimensional (2D) nanomaterials with noble metals significantly develops sensors' performance parameters such as sensitivity, figure of merit, and detection accuracy. 2D nanomaterials such as graphene, black phosphorus (BP), MXenes, and transition metal dichalcogenides (TMDCs), significantly improve performance parameters and protect metal layers against oxidation. Prism-based surface plasmon resonance (SPR) sensors have significant advantages over other optical sensors, including remarkable sensitivity, high accuracy and response speed, label-free detection, high resistance to environmental temperature changes, and the possibility of detecting molecules biological with low concentration and volume. In this review paper, the history and current status of plasmonic biosensors based on the Kretschmann configuration are investigated, focusing on 2D materials, and their potential applications in various fields, especially medicine, are evaluated. Moreover, the phenomenon of surface plasmon resonance and plasmons stimulation methods for sensing and biosensing purposes has been introduced. New numerical and analytical approaches for modeling plasmonic biosensors and determining their performance parameters have also been investigated. This review paper can be useful for the scientific community who are interested in research in the field of plasmonic biosensors.
