Nanotechnology and Acoustics in Medicine and Biology

Background: Nanotechnology plays an important role in various engineering fields, one of which is acoustics. Method: Here, we review the use of nanotechnology in multiple acoustic-based bioapplications, with a focus on recent patents and advances. Nanoparticles, nanorods, nanotubes, and nanofilms used in acoustic devices are discussed. We cover ultrasonic transducers, biosensors, imaging tools, nanomotors, and particle sorters. Results and conclusion: The way these ideas help in fundamental disciplines such as medicine is shown. We believe the current work is a good collection of advances in the field.
