摘要: A metal nanoantenna for use in a biosensing device is disclosed. The metal nanoantenna is arranged to exhibit at least two particle plasmon resonances or surface plasmon resonances (SPRs). The nanoantenna is for use in a sensor and allows detection at low concentration of biological components. In one aspect, the nanoantenna can have an asymmetric structural configuration and spectrally separated resonances. In one aspect, there is a location in its structure providing local electromagnetic field enhancement at all of the SPRs. The metal nanoantenna can be used for background free measuring of a quantity of a biological component.
