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.

Abstract translation: 一种粒子感测系统，其包括将来自未聚焦或松散聚焦的光源的光聚焦到包含等离子体激元结构的表面上的对应的多个聚焦区域上的多个微透镜。 聚焦区域中等离子体结构对光的吸收导致等离子体激元结构中的散热并因此增加了聚焦区域中的表面温度。 当将电场施加到与表面接触的样品流体时，在流体中引起多个电热流，其迅速将悬浮颗粒传输到表面上的聚焦区域。 然后可以捕获和/或感测颗粒。
