July 2020 - 7 articles

Cover Story: Plasmonic fiber-optic biosensors combine the flexibility and compactness of optical fibers and high sensitivity of plasmonic nanomaterials to their surrounding medium, to detect biological species such as cells, proteins, and DNA. By tracking the variations in light absorption or energy loss maxima, one can detect an unknown analyte molecule bound to the surface of plasmonic nanoparticles or detect an unknown liquid analyte that is in direct contact with a plasmonic nanofilm. Due to their small size, accuracy, low-cost, and possibility of remote sensing, plasmonic fiber-optic biosensors are promising alternatives to traditional methods for biomolecule detection and can result in significant advances in clinical diagnostics, drug discovery, food process control, disease, and environmental monitoring.
