Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
In chemistry, a reaction is spontaneous when it does not need the addition of an external energy input. How much energy is released in a reaction is dictated by the laws of thermodynamics. In the case of the spontaneous reactions that occur in the human body this is often not enough to power medical implants. Now, scientists at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international team of researchers, found a way to boost the energy output by storing and bundling the energy of many spontaneous enzyme reactions. The work is published in the journal Nature Communications and shows how abundant, simple enzyme reactions can be used to power energy-hungry reactions and electronic devices.

The 2017 International conference on micro- and nanomachines will be held in Wuhan, China, from the 25-28 August and will be co-chaired by Peer Fischer
Peer Fischer, head of the Research Group "Micro-, Nano- and Molecular Systems" at the Max Planck Institute for Intelligent Systems and Professor of Physical Chemistry at the University of Stuttgart, was awarded with a Steinhofer lecture 2017 of the University of Freiburg "for his fundamental work in the field of targeted 3D-production of artificial nanostructures and their application in biomedicine". Professor Fischer gave his lecture on "How to Teach Nanoparticles and Enzymes to Swim".
