Townsend, R, Hill, M, Harris, NR, Stacey, SP, Kuznetsova, LA, Borthwick, KAJ and Coakley, WT (2006) Acoustic Particle Manipulation to Enhance the Sensing of Cells within Microfluidic Chambers At 17th MicroMechanics Europe. 03 - 05 Sep 2006. , pp. 193-196.

Record type: Conference or Workshop Item (Poster)


The sensing of cells within micro-fluidic components can be greatly enhanced by maximizing the concentration of particles around the sensor element. To encourage bacterial cells to move to a surface, acoustic radiation forces are employed, which rely on the compressibility and density of the particulate matter. This provides an alternative to electric or magnetic field-assisted particle manipulation, and can operate over greater length scales. This paper describes the simulation of a device used to demonstrate the principle and reveals how the geometric design of the system influences the acoustic field and is paramount to the particle manipulation process. Predictions of particle concentrations upon a surface compare excellently with experimental results
