A futuristic nanowire device may offer people the possibility of wearable, personal-cooling devices, according to a new study. The devices could be a lifesaver for firefighters, astronauts, soldiers and anybody outside on the hottest summer days, the research team from Penn State write in the journal Advanced Materials. “This low voltage is good enough for […]
Killing cancer with chemotherapy is a lot like a drone strike. The targeting is rarely precise enough to avoid collateral damage. Recently, researchers have been dreaming about killing tumours – while not further damaging a sick person – with seek-and-destroy nano-robots that would carry their deadly payloads through the body and only unleash them on cancer […]
Scientists from the California NanoSystems Institute at UCLA have developed a nanoparticle delivery system for the antibiotic moxifloxacin that vastly improves the drug’s effectiveness against pneumonic tularemia, a type of pneumonia caused by inhalation of the bacterium Francisella tularensis. The study, which appears in the journal ACS Nano, shows how the nanoparticle system targets the […]
“Poets say science takes away from the beauty of the stars, mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?” A gorgeous hypothetical question from the late great Nobel Prize winning physicist, Richard Feynman. And just last week the […]
Dear Clerk Allan, Nano-Structures & Nano-Objects a new Elsevier journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. ‘Synthesis is the basis of chemistry and at the core of this scientific discipline. A compound or a material has first to be made before its properties can be investigated […]
Creating swarms of soft, robotic hands that can safely dissolve within a living body once they’ve performed surgical procedures or delivered drugs just got a step closer thanks to work done by John Hopkins University scientists. They’ve created minute biodegradable microgrippers by adding stiff polymers containing magnetic nanoparticles to soft hydrogels, allowing them be magnetically […]
