A novel and sensitive multi-throughput localized surface plasmon resonance (MLSPR) biosensor was developed for the first time. Various gold nanorods with different aspect ratios were used to fabricate the optical sensor. Five kinds of gold nanorods with different aspect ratios were chosen to constru...
