Congratulations to Udit Choudhury for defending his thesis on the "Dynamics of self-propelled colloids and their application as active matter", and best of luck as he is leaving the group to start a Postdoc at AMOLF in the Netherlands.
Congrats and good luck to Dr. Dhruv Singh
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.
