Abstract
We present an experimental study to analyze the influence of the chip material on acoustophoresis processes induced by ultrasounds in microfluidic devices. Two materials with different acoustic properties were used for the chip structure: glass and PMMA respectively. Different vibrations established in their respective structures give rise to diverse acoustic pressure patterns within the liquid phase of the channels, providing different particle collection efficiencies. Advantages and disadvantages of both types of chips have been tested.
