Abstract
Method and apparatus for the single particle detection of submicron structures such as biological molecules and viruses utilises and optically transparent substrate coated with a thin film of metal illuminated with an optical beam incident at or close to critical or SPR angle wherein part of the beam propagates along the metal surface defining a measurement zone from which submicron particles contained in a sample placed in contact with the metal film scatter light which can be detected in the far field by conventional photodetection systems. The apparatus can be configured in a flow cytometric of optical microscope configuration.
