Abstract
A device for the detection of analytes comprises a substrate () with nano-antennas (). The nano-antennas () comprise an antenna material (m,m) for forming resonant antenna structures which receive and resonantly interact with source light (L) to form respective resonance peaks (R,R) over a resonant wavelength range (A,A) overlapping respective signature wavelength (λ) of a target analyte (A). The resonant interaction causes a locally concentrated field (Ec) of the source light (L) in the resonant wavelength range (Λ). The concentrated intensity (Ic) is localized around a respective target location (T,T) which is provided with a sorption material () that sorbs the target analyte (A). This provides a locally increased analyte concentration (Ac) of the target analyte (A) coinciding with the locally concentrated field (Ec) of the source light (L). Accordingly, the interaction of the source light (L) with the target analyte (A) is enhanced.
