Integrated Optical Sciences
Biomolecules and nanostructures
The Optical Sciences group studies the interaction of light and matter at the nanoscale.
We do this by exploring ways to shape light and its environment. It's what we call
active and passive control. Our current focus is on the interaction of light with
biomolecules and nanostructures. We are part of Twente
University's Department of Science and Technology and member of the
Particle manipulation by ultrasonic waves
The goal of this project the goal is move particles to a specific position within a liquid using high frequency acoustic waves. This is done by applying a standing pressure wave on particles in a flow. Due to the difference in compressibility, particles tend to align on the nodes and by moving the nodes of the standing waves, the particles can be moved towards the side of the flow channel. Since this technique can be used for a wide variety of particles, applications range from (microbiological) analysis of drinking water to filtering of contaminated water in petrochemical industries.
