Contactless Micromanipulation with Acoustic Waves
A promising way to handle and manipulate matter at the microscale is to use the acoustic radiation stresses (force and torque) that originate from the interaction between an incident wave and a target. Single-beam acoustical tweezers have recently been developed to trap, manipulate and study individual objects of interest at the microscale (e.g. droplets, bubbles, soft matter and biological structures) without any physical contact.
We investigate the physical mechanisms of various wave/matter interactions by systematically combining theoretical models with innovative experimental setups that integrate advanced acoustical and optical techniques. These include wavefront shaping, fibre-optic pressure measurements, and high-speed optical microscopy.
