Disclosed herein is a plasmonics platform comprising a substrate; a
plurality of periodically spaced nanoholes and/or nanoparticles disposed
upon the substrate; wherein the average first order of periodicity
between the nanoholes and/or the nanoparticles is about 5 to about 1,000
nm; and a microelectromechanical and/or a nanoelectromechanical system in
operative communication with the substrate so as to vary the average
first order of periodicity between the nanoholes and/or the
nanoparticles.
