A sensor for detecting of an analyte in a solution phase comprises a plurality of functionalised silver nanoplates wherein a functionalising agent is directly bonded to the surfaces of the nanoplates. The nanoplates provide a detectable wavelength shift change in their local surface plasmon resonance spectrum in response to the binding of an analyte. Two or more of the nanoplates may be electromagnetically coupled.
