Scientists from the Max Planck Institute for Medical Research and the Heidelberg University created "acoustic holograms" that would offer a novel way of assembling matter into a 3D object, as per a press release.
Their design creates pressure fields using several acoustic holograms, which can be used to print solid particles, gel beads, and even living cells. These results may pave the path for cutting-edge 3D cell culture methods with biomedical engineering applications.
