Nanobiomimetic strategies for medicine

The defenses of the body's immune system tend to destroy synthetic nanoparticles and frequently they are captured and removed from the body within few minutes. This, of course, is a major barrier to the use of nanotechnology in medicine. In order to evade the host immune response, researchers are demonstrating that the combination of nanomaterials and biomimetic strategies can change diverse nanomaterials from 'distinguishable state' to 'camouflage state' and thereby improving technologies for nanomedicine applications.

Nanopowder ceramics - in control of chaos

Crystals consisting of wildly mixed ingredients - so-called high-entropy materials - are currently attracting growing scientific interest. Their advantage is that they are particularly stable at extremely high temperatures and could be used, for example, for energy storage and chemical production processes.
