Low concentration oil separation and detection from environmental water samples through acoustophoresis Conference Paper uri icon

abstract

  • Detecting low concentrations of oil has immense importance in marine environment monitoring, especially in the case of large-scale oil spill and chronic oil discharge. Current fluorescence based oil detectors have trade-offs between detection sensitivity and portability/cost. A microfluidic low concentration oil droplet trapping and detection system was developed based on acoustophoretic droplet manipulation that oil droplets in water move towards acoustic pressure antinodes and can be separated or trapped, facilitating highly sensitive fluorescent detection of accumulated oil droplets from environmental samples. The developed oil detection system is expected to be used as a portable and field-deployable low-cost oil spill detector.
