Abstract

An example micro-fluidic device includes a micro-fluidic channel having an inner surface and a plurality of pillars positioned along the inner surface. The device further includes a plurality of power supplies connected to the pillars. Another example micro-fluidic device includes a micro-fluidic channel having an inner surface and a plurality of pillars positioned along the inner surface. The device further includes a power supply. The pillars are grouped into at least two groups of pillars, each group of pillars including at least two pillars, and all pillars of at least one group of pillars are connected to the power supply. In another example, a sensing system for detecting bioparticles includes a micro-fluidic device, wherein a surface of each pillar comprises functionalized plasmonic nanoparticles or functionalized SERS nanoparticles, a radiation source for radiating the micro-fluidic device, and a detector for detecting SERS signals or surface plasmon resonance.
