Breaking through Barriers: Ultrafast Microbullet Based on Cavitation Bubble (Small 18/2023)

Abstract

Ultrafast Microbullets As the excited cavitation bubble expands and collapses close to the polystyrene (PS)/ magnetic nanoparticle (MNP) microbullet, a high pressure is generated, which violently propels the microbullet to realize its hurtling motion. This enormous energy of the cavitation bubble is expected to provide the microbullet with the ability to break through barriers such as reservoir boundaries.
