Fabrication and Characterization of the Fiber Optical Taper for a Surface Plasmon Resonance Sensor
For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...
متن کاملDevelopment of Au Nano-particles Cladding-doped Optical Fiber for Surface Plasmon Resonance Sensor Applications
A novel optical fiber having its cladding doped with Au nano-particles was developed by modified chemical vapor deposition process. Absorption peaks of the optical fiber preform and the fiber appearing at 585 nm and 428 nm, respectively were due to surface plasmon resonance (SPR) of the incorporated Au nano-particles in the cladding. The measured peak wavelength of the SPR was found to increase...
متن کاملFiber Surface Modification Technology for Fiber-Optic Localized Surface Plasmon Resonance Biosensors
Considerable studies have been performed on the development of optical fiber sensors modified by gold nanoparticles based on the localized surface plasmon resonance (LSPR) technique. The current paper presents a new approach in fiber surface modification technology for biosensors. Star-shaped gold nanoparticles obtained through the seed-mediated solution growth method were found to self-assembl...

متن کاملOptical Fiber Sensor Based on Localized Surface Plasmon Resonance Using Silver Nanoparticles Photodeposited on the Optical Fiber End
This paper reports the implementation of an optical fiber sensor to measure the refractive index in aqueous media based on localized surface plasmon resonance (LSPR). We have used a novel technique known as photodeposition to immobilize silver nanoparticles on the optical fiber end. This technique has a simple instrumentation, involves laser light via an optical fiber and silver nanoparticles s...
