Powering a pacemaker with a patient’s heartbeat

20.02. 2019 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Implantable pacemakers have without doubt altered modern medicine, saving countless lives by regulating heart rhythm. But they have one serious shortcoming: Their batteries last only five to 12 years, at which point they have to be replaced surgically. Now, researchers have surmounted this issue by designing a pacemaker powered by the energy of heartbeats, according to a report in ACS Nano. The device was successfully tested in pigs, which have a similar physiology to humans.

Breakthrough in the search for graphene-based electronics

19.02. 2019 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

For 15 years, scientists have tried to exploit the "miracle material" graphene to produce nanoscale electronics. On paper, graphene should be great for just that: it is ultra-thin—only one atom thick and therefore two-dimensional, it is excellent for conducting electrical current, and holds great promise for future forms of electronics that are faster and more energy efficient. In addition, graphene consists of carbon atoms – of which we have an unlimited supply.

Nano-droplets are the key to controlling membrane formation

19.02. 2019 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

The creation of membranes is of enormous importance in biology, but also in many chemical applications developed by humans. These membranes are shaped spontaneously when soap-like molecules in water join together. Researchers at Eindhoven University of Technology now have a clear picture of the entire process. Membrane formation turns out to start with nano-droplets in the water with a higher concentration of soap-like molecules. If you can control those nanodroplets, you can control shape, thickness and size of the membranes. This is of great importance for, among other things, the development of new nanomedicines. The results are published in Nature Chemistry.
