Acoustic particle detection (2016-17) (2016-17)

Acoustic manipulation can be used for the arrangement of biological cells and microscale objects that plays an important role in many biological and colloidal studies, such as microarrays, regenerative medicine, and tissue engineering. One of the techniques to manipulate particles is acoustic tweezing. This technology is based on acoustic standing waves. The unique advantage of multi-element acoustic tweezers is the possibility in manipulating and sensing.
The following project proposes to explore sensing and detecting particle concentrations, particle density and topography. Each particle/cell have a unique fingerprint and our prototype explores the capability of detection.
A. The student will use two different acoustic tweezer devices based on multi-element surface acoustic wave technology (glass cover slip and PDMS chamber). The students will perform a series of experiments:
• with different concentration of particles,
• with different density of particles,
• with different mixture of particles.
B. The student will also investigate patterning particles and imaging this pattern by topography techniques.

The student need to be highly motivated and have a good understanding of the physics of waves and a knowledge of electronics. The students will also need to showcase experimental skills. The experimental work will take place using a high-end microscope. This project does not aim for publications or dissemination.
