Abstract
LSPR properties of bioconjugated gold nanoparticles are exploited in realizing evanescent wave absorbance based fiber optic sandwich immunosensor. In addition, a method to amplify the sensor response by about 2-5 times by using high refractive index medium around nanoparticle labels is demonstrated.
