Optical Fiber and Plasmonic Resonance Sensors for Chemical and Biological Detection
This community develops high-sensitivity sensors based on optical fibers and surface plasmon resonance to detect changes in refractive index, temperature, and specific biological or chemical analytes.
The work centers on integrating photonic crystal fibers, Bragg gratings, and surface plasmon resonance (SPR) structures to create devices for detecting analytes such as glucose, cancer biomarkers, and environmental contaminants. Recurring materials include gold, silver, and graphene oxide, often used to enhance sensitivity in fiber-based or planar configurations. Applications span medical diagnostics, such as detecting SARS-CoV-2 or cancer cells, and industrial monitoring, including temperature and humidity sensing. The community also explores machine learning algorithms to optimize sensor design and signal processing, with a strong focus on improving detection limits and specificity for complex samples like blood or biological fluids.
The largest share of the community's output is found in gold research, accounting for 0.6% of all gold research, with 1,257 papers in this group. Carbon and silicon follow, contributing 1,115 and 808 papers respectively, representing 0.1% and 0.2% of their respective element research.
The community comprises 11,629 papers, published primarily in Optical Fiber Technology, Optics & Laser Technology, and Plasmonics.
Recent work continues to focus on SPR biosensors for cancer biomarker detection and disease diagnosis, with several 2025 papers describing novel fiber-based designs for detecting specific antigens and viral variants.
