Use of the SPRi method in safety and security applications

Abstract

Surface plasmon resonance (SPR) is emerging as an important tool in security, particularly for detecting a wide range of hazardous substances. It enables rapid and sensitive detection of bacterial toxins, pathogens, biomarkers, chemicals, and narcotics. Studies have confirmed its effectiveness in identifying substances with bioterrorism potential—such as anthrax and botulinum toxin—as well as pesticides, nerve agents, and drugs in body fluids. Compared to traditional analytical methods, SPR offers a faster, cheaper, and simpler alternative with high reproducibility. This article provides an overview of SPR applications in security and highlights its potential for protecting public health and preventing bioterrorism.
