Miniaturized robots can be propelled through biological fluids by an enzymatic reaction or ultrasound
Nanorobots and other mini-vehicles might be able to perform important services in medicine one day – for example, by conducting remotely-controlled operations or transporting pharmaceutical agents to a desired location in the body. However, to date it has been hard to steer such micro- and nanoswimmers accurately through biological fluids such as blood, synovial fluid or the inside of the eyeball. Researchers at the Max Planck Institute for Intelligent Systems in Stuttgart are now presenting two new approaches for constructing propulsion systems for tiny floating bodies. In the case of one motor, the propulsion is generated by bubbles which are caused to oscillate by ultrasound. With the other, a current caused by the product of an enzymatic reaction propels a nanoswimmer.
Our nanorobots are the topic of a special report on robots in the newspaper Die Zeit and Der Spiegel has previously covered our research, also highlights our work in its 2017 March 11 issue.
Dr. Peer Fischer, head of the Micro- Nano- and Molecular Systems Lab at the Max Planck Institute for Intelligent Systems and Professor of Physical Chemistry, University of Stuttgart, has received the World Technology Award 2016. Professor Fischer was selected among 32 nominees and then among six finalists in the category “Information Technology – Hardware” that recognizes achievements in the field of IT hardware, including such significant subcategories as manufacturing and robotics.
A new way of shaping sound waves in 3D aids technology and could be useful for medical ultrasound applications
Sound can now be structured in three dimensions. Researchers from the Max Planck Institute for Intelligent Systems and the University of Stuttgart have found a way of generating acoustic holograms, which could improve ultrasound diagnostics and material testing. The holograms can also be used to move and manipulate particles.
