Feng Guo, Ph.D., of Indiana University Bloomington will present a lecture entitled: Acoustic Tweezers: Manipulating Cells Using Sound Waves.
Abstract: Abstract: Sound can be music to please the ear, however the waves produced can be utilized as “Acoustic Tweezers” for the manipulation of cells and particles in a fluid medium. The acoustofluidics technology, combining sound waves with fluidics, becomes a revolutionary way to dexterously and noninvasively manipulate biological specimens. Firstly, this technique manipulates cells or particles using gentle mechanical vibrations. These vibrations create a pressure gradient in the medium to move suspended micro-objects yielding a contamination-free, contactless, and label-free manipulation. Secondly, acoustofluidics has minimal impact on cell integrity and function. Thirdly, this technology can operate in a single, inexpensive micro-device without complicated setups, which offer additional advantages in ease of use, versatility and portability. Here, we report a series of acoustic tweezer devices for the manipulation of living cells in a microfluidic environment to address the problems in the field of biomedicine including cancer immunotherapy, 3D spheroids/organoids, and neurosciences.
