The next generation of electronic hardware security may be at hand as researchers at New York University Tandon School of Engineering introduce a new class of unclonable cybersecurity security primitives made of a low-cost nanomaterial with the highest possible level of structural randomness. Randomness is highly desirable for constructing the security primitives that encrypt and [...]
Bacteria are able to attach themselves to tissue fibers with the aid of a ‘nano-adhesive’. Just how they achieve this was investigated a few years ago by Viola Vogel, Professor of Applied Mechanobiology, using computer simulations at CSCS. The researchers simulated how the bacterial nano-adhesive – a peptide thread with several binding sites strung together [...]
University of Illinois researchers are sending tiny drug-laden nanoparticles on a mission to seek and destroy cancer stem cells, the elusive and rare cells that can cause cancer to come back even when years have passed since the initial tumor was treated. In a study led by Dipanjan Pan, an Illinois professor of bioengineering, researchers [...]
From an article at azonano.com, written by Shelley Stoakes: Nanotechnology is currently being applied to innovative methods of medical imaging. The development of imaging at the nanoscale has the ability to enhance the field of medicine by providing more detailed images of cellular processes. Current methods of medical imaging are being adapted to increase their [...]
While people protect their eyes from the sun’s radiation during a solar eclipse, NASA’s Human Research Program (HRP) is working to protect the whole human body from radiation in space. Space radiation is dangerous and one of the primary health risks for astronauts. “Determining astronaut health consequences following radiation exposure involve very [...]
A surprise finding suggests that an injection of nanoparticles may be able to help fight the immune system when it goes haywire, researchers at the University of Michigan have shown. The nanoparticles divert immune cells that cause inflammation away from an injury site. Inflammation is a double-edged sword. When it works, it helps the body [...]
In the last few years, the number of eye surgeries for conditions including glaucoma and cataracts has greatly increased and with it, so has the number of potentially blinding intraocular infections. In a recent study, researchers demonstrate using a mouse model that engineered nanosponges can be employed to protect eyes from infections caused by Enterococcus [...]
Moderate exposure to sunlight has significant health benefits – vitamin D production, beneficial modulation of blood pressure, and psychological effects of well-being. However, exposure to ultraviolet (UV) radiation also is a major risk factor for most skin cancers. That means that, while moderate exposure to sunlight is recommended, there is a fine line to walk [...]
Human genome editing, 3D-printed replacement organs and artificial photosynthesis - the field of bioengineering offers great promise for tackling the major challenges that face our society. But as a new article out today highlights, these developments provide both opportunities and risks in the short and long term. Rapid developments in the field of synthetic biology [...]
Gold nanoparticles could help make drugs act more quickly and effectively, according to new research conducted at Binghamton University, State University of New York. Nanoparticles are microscopic particles that are bigger than atoms but smaller than what the eye can see. They are unique for their large surface area-to-volume ratio and their fairly ubiquitous nature. [...]
