When studying dangerous pathogens, physical contact must be avoided to minimize the risk of infection and contamination to researchers. To address this, researchers at Virginia Tech have developed a new technology that can manipulate cells without physical touch. Using acoustic-dielectric tweezers—a technology integrating acoustic waves and electric fields—they can capture and move biological particles like cells and viruses. In their study, published in Science Advances in August 2024, the researchers utilized high-frequency acoustic waves to trap cells in a grid pattern and then controlled their movement with electric fields. This technology enables scientists to study and manipulate cells without direct contact, significantly reducing risks to researchers, especially when handling pathogens. Furthermore, this advancement marks a breakthrough in disease diagnosis, treatment, and prevention.
