The immune system's activation of macrophages, a type of immune cells that are on the lookout for pathogens, is a major obstacle for developing functional medical microrobots that can operate in vivo for a prolonged period of time. Researchers are trying to overcome this challenge by 'camouflaging' therapeutic nanoparticles with special coatings so that they avoid detection by macrophages. In new work, researchers report the development of stealth microrobots that can fly under the radar of the immune system, and hence prolong their window of operation since they do not get eliminated.

Scientists has synthesized graphene nanoribbons on a titanium dioxide surface using an atomically precise method that removes a barrier for custom-designed carbon nanostructures required for quantum information sciences.
Nanoengineers are getting ready to rev their engines for the second international Nanocar Race.
An inexpensive, accessible and non-invasive therapy for diseases and injuries of the brain may be slowly emerging: tiny particles called extracellular vesicles (EVs). Unlike stem cell therapies for repairing brain damage, EVs may safely regenerate brain cells and reduce inflammation.
Engineers have found a 2D material that could make computers faster and more energy-efficient. Their material is a derivative of perovskite that has the surprising ability to enable the valleytronics phenomenon touted as a possible platform for information processing and storage.
Researchers demonstrate that gold nanotubes could be used to treat mesothelioma, a type of cancer caused by exposure to asbestos.
The new instrument, based on the principle of a quartz-crystal microbalance combined with a graphene-based bio-interface, offers a cheap, fast, simple and sensitive alternative to currently available antibody tests.
