The developed microgripper demonstrates: 🔹 Ultrafast actuatio

Nelson, and Salvador Pané Several nanomaterials have been proposed for antibacterial applications,offering promising strategies to combat infections as antibiotic resistancecontinues to rise due to widespread misuse. However, their clinical translation remains limited by poor localization and the lack of active control at the

By: Alen Pavlič and Thierry Baasch Acoustic forces occurring in resonant microfluidic chambers allow the handling of micrometer-sized particles. Trapping of nanoparticles has been shown for high particle concentrations and after preseeding the chamber with larger particles. We show that the trapping mechanism is due to synergy between hydrodynamic shielding and acoustic forces. Acoustic interactions are significant only when seed particles are involved and are negligible when
