Webb, Lutalo ; Hastings, J. Todd
Abstract :
Dual-mode surface-plasmon resonance (SPR) sensors use both long- and short-range surface-plasmon waves to differentiate surface binding interactions from interfering bulk effects. Typically, a thin layer of gold is used in these sensors. However, research shows silver is theoretically a more suitable candidate. This paper examines following: the optical properties of silver; how the optical properties of silver change with various deposition techniques; and whether silver is a superior metal for dual-mode SPR sensors.
