초록
Various etching methods of optical fiber and formation of metal nano particles on the optical fiber have ben proposedfiber are possible by removing the cladding of optical fiber using HF (hydrofluoric acid) solution and BHF (bufferedhydrofluoric acid) solution, which results in improved surface roughness when BHF solution is used. Localized surfaceplasmon can be formed and measured by formation of silver and gold nano particles on the etched optical fiber. Thecharacteristics of the etched optical fiber and metal nano particles on the etched surface of the optical fiber play a keyrole in dictating the sensitivity of the LSPR sensors, so that the proposed results can be expected to be applied for relatedresearch on fiber optic based biosensors.
