A group of researchers from the Nanyang Technological University (Singapore) have succeeded in developing a new type of d3D printed device It can take advantage of high-pressure ultrasound to move, manipulate, and even destroy particle-sized objects, droplets, and even biological tissue on scales comparable to cells. Undoubtedly a device that can be tremendously useful in fields such as surgery thanks to the fact that it can provide unprecedented control in photoacoustic waves.
As discussed in the paper published by this group of researchers, control in this field is essential and previous devices could only produce basic types of acoustic waves that, using a thin layer of carbon nanotubes installed on a glass surface, produced the vibrations necessary to produce high frequency and high pressure acoustic waves. Unfortunately and due to the fact that this material used is based on glass, in this new project it has been achieved that this material becomes a clear liquid resin lens. For its manufacture, a state-of-the-art 3D printer had to be used.
A group of researchers manages to develop a new device capable of channeling and orienting ultrasound.
Thanks to the use of precisely a 3D printer, scientists were free to create a lens of any shape, thus allowing them to generate acoustic waves of any shape. Thanks to this, researchers can now focus the waves at multiple points at the same time, or they can control the phase of the waves and direct them at different points at different times. As announced, this new device will help eye surgeons to perform cataract surgery since now acoustic waves can be used to measure the elastic properties of cells in a Petri dish, seeing how they respond to forces.
