Cells continuously replicate to repair and replace damaged tissue, and each division requires a reprinting of the cell's genetic blueprints. As the DNA duplicates, errors inevitably occur, resulting in damage that, if left unrepaired, can lead to cellular death. At the first hint of DNA damage, a protein known as an ATR kinase activates the [...]
Researchers from the University of Minnesota College of Science and Engineering have found yet another remarkable use for the wonder material graphene—tiny electronic “tweezers” that can grab biomolecules floating in water with incredible efficiency. This capability could lead to a revolutionary handheld disease diagnostic system that could be run on a smart phone. Graphene, a [...]
A new method for delivering chemotherapy nanodrugs capable of increasing the drugs’ bioavailability and reducing side-effects has been developed by Carnegie Mellon University researchers. Their study has been published online in Scientific Reports and it demonstrates that administering an FDA-approved nutrition source before chemotherapy can help reduce the quantity of the toxic drugs that settle [...]
A feature of science fiction stories for decades, nanorobot potential ranges from cancer diagnosis and drug delivery to tissue repair and more. A major hurdle to these endeavors, however, is finding a way to cheaply make a propulsion system for these devices. New developments may now propel nanoswimmers from science fiction to reality thanks to [...]
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 [...]
