| Abstract |
Biosensing based on the localized surface plasmon resonance of metallic nanostructures is a powerful tool for the detection of target species. To increase sensitivity, the systematic synthesis of complex nanostructures along with the design of a sensing platform with a rational configuration is critically important. However, most LSPR-based sensors operate in a passive and static way, hindering further improvements to their sensitivity and detection time. Herein, we report an unprecedented active and dynamic sensing platform based on a LSPR configuration that is modulated by using an external magnetic field. Electrochemically-synthesized Au/Fe/Au nanorods exhibited plasmonically-active behavior through plasmonic coupling, and the middle ferromagnetic Fe block responded to a magnetic impetus, allowing the nanorods to be modulated. The shear force variation induced by the specific binding events between antigens and antibodies on the nanorod surface is used to enhance the sensitivity of detection of antigens in the plasmonics-based sensor application. As a proof-of-concept, influenza A virus (HA1) was used as a target protein. This conceptual sensing method provides a new platform for active plasmonic-magnetic biosensing. |
