Caption: This image shows experimentally collected spectra from the trapped fluorescent microbead-BNA system (inverted orientation) with horizontal and vertical polarization (parallel and perpendicular to the bowtie axis, respectively). The reference is taken from a microbead trapped away from the arrays in the inverted orientation. The inset image depicts the dramatic fluorescence enhancement when the particle is moved onto the array (indicated by the yellow outline). The scale bar is 5 um.
