Conceptual image of an acoustofluidic tweezing device using ring resonator technology to control micron-sized particles in fluids. Xu et al. combined acoustic waves with a high Q factor to create stronger and more precise trapping zones. This allows for non-contact particle manipulation and minimizes heat generation and bubble formation. The technology holds promise for advancing fields such as biosensing, tissue engineering, and lab-on-a-chip applications, opening doors to non-contact, more effective particle manipulation in scientific and medical research.
