Abstract
Dark-field microscopy in a surface plasmon resonance (SPR) scheme is introd uced. A nanometre-thick patterned coating was imaged with SPR, and the imag e contrast was drastically enhanced when the zero diffraction order was eli minated. The resulting contrast is assigned to abrupt changes of the light phase with coating thickness, which are specific to SPR. The method offers prospects for highly sensitive multiple-spot biosensors.
