Polymeric antibubbles with strong ultrasound imaging capabilities.

Chem Commun (Camb)

November 2024

Institute for Experimental Molecular Imaging, RWTH Aachen University Hospital, Aachen 52074, Germany.

Antibubbles are liquid droplets encapsulated by a gas film that have recently been explored for on-demand ultrasound-triggered drug release. However, their ultrasound imaging capabilities are limited by their stiff shells stabilized with silica nanoparticles. Here, we develop polymeric antibubbles that generate greater ultrasound contrast than silica-based antibubbles, while showing better stability than conventional polymeric microbubbles.
