Abstract
A particle sensing system which includes a plurality of micro-lenses which focus light from an unfocused or loosely focused light source onto a corresponding plurality of focus regions on a surface containing plasmonic structures. The absorption of light by the plasmonic structures in the focus regions results in heat dissipation in the plasmonic structures and consequently increases surface temperature in the focus regions. When an electrical field is applied to a sample fluid in contact with the surface, multiple electrothermal flows are induced in the fluid which rapidly transport suspended particles to the focus regions on the surface. The particles can then be captured and/or sensed.
