AI Technical Summary
Existing HIFU technologies require high power levels for both mixing and lysis, complicating the use of a single chamber and necessitating large transducers and liquid cooling, which can lead to excessive heating and material degradation.
The apparatus focuses high-intensity ultrasound waves on the liquid-air interface within a cartridge, creating a fountain that induces heterogeneous cavitation with a reduced power threshold, allowing for smaller transducers and solid-state coupling, thereby avoiding material degradation and enabling miniaturization.
This approach reduces the power required for cavitation, enabling smaller transducers, minimizing material degradation, and allowing for complete dry coupling, thus reducing costs and contamination risks while maintaining effective sample treatment.
