Analysis and interpretation of bimetallic plasmonic metamaterial properties for forensic applications

Abstract

Plasmonic biochemical sensors, as a subgroup of optical refractometric sensors, are a topic of rapid research and development due to their ability to detect trace amounts of biochemical agents, even allowing detection of a single molecule. As such, plasmonic sensors find wide applications in forensic engineering, medicine and clinical diagnostics, food processing, environmental protection, and many more. Additionally, the use of plasmonic metametrials is not limited to sensing, and they can be used in various fields paramount to forensic sciences, such as enhanced microscopy and spectroscopy, photodetector enhancement (entire optical range – UV, VIS, and IR light), signal processing, etc.
