Lab on a Chip Paper
in contrast to the standard quadrupolar flow roll structure
generated by a one-dimensional half-wavelength resonance.
The ability to manipulate bacteria and other submicrometer
particles in a half-wavelength ultrasound standing
wave field opens up the acoustophoresis research field
to new applications in microbiology. Future research will
concentrate on using the new method to generate systems
capable of reducing diagnosis and detection times in the biomedical
field, and in environmental and food applications.
