Foundational work has demonstrated that acoustic fields using DIY platforms like TinyLev can transport and process droplets and particles in air without mechanical contact, supporting the concept of contactless material handling.

Acoustic levitation enables particles and microscopic samples to be studied away from solid surfaces, reducing substrate artefacts during optical, spectroscopic, or scattering-based analysis.

Acoustic levitation has been used as a model platform for coating individual pellets while monitoring the process, showing its relevance to pharmaceutical coating, seed coating, and particle treatment research.

Acoustic fields can influence particle-particle interactions, promoting clustering or agglomeration under controlled conditions. This is both a challenge and an opportunity for powder research.

Acoustic manipulation offers a route to explore low-volume transfer of difficult powders where residue, dead volume, adhesion, or mechanical handling dominate the workflow.
