Abstract
A sensor element comprises a metallic nanostructure formed at edges of at least two microelectrodes on a non-electrically conductive substrate. The nanostructure is formed by depositing a solution comprising at least one metal salt and a stabilizing agent on the substrate at a detection site between the microelectrodes, and applying an AC electric field to the electrodes. The sensor elements may be used in sensing platforms such as surface-enhanced Raman scattering (SERS), surface plasmon resonance (SPR), localized surface plasmon resonance (LSPR), and in electrical-based sensing such as electrochemical sensing.
