음향 부상 시스템에서 Nonspherical Bubble Oscillations에 의한 마이크로스트리밍 유도

Executive Industry Relevance

Controlling nonspherical microbubble oscillations in an acoustic levitation system enables precise study of cavitation microstreaming and its mechanical effects on biological barriers. This capability is strategically relevant for biopharma R&D seeking to optimize ultrasound-mediated drug and gene delivery by enhancing cell membrane permeability in a controlled, localized manner. The approach supports predictive confidence in mechanistic de-risking at the interface of discovery biology and translational research.

Strategic Applications in Biopharma R&D
