Self-replicating nanostructures made from DNA

(Phys.org)—Is it possible to engineer self-replicating nanomaterials? It could be if we borrow nature's building blocks. DNA is a self-replicating molecule where its component parts, nucleotides, have specific ...

Nanosilver and the future of antibiotics

Precious metals like silver and gold have biomedical properties that have been used for centuries, but how do these materials effectively combat the likes of cancer and bacteria without contaminating the ...

Non-aqueous solvent supports DNA nanotechnology

Scientists around the world are using the programmability of DNA to assemble complex nanometer-scale structures. Until now, however, production of these artificial structures has been limited to water-based ...

Engineering phase changes in nanoparticle arrays

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be ...

Gel filled with nanosponges cleans up MRSA infections

Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant ...

Exposing breast cancer using nanoscale polymers

Photoacoustic imaging is a ground-breaking technique for spotting tumors inside living cells with the help of light-absorbing compounds known as contrast agents. A*STAR researchers have now discovered a way ...

Cotton fibres instead of carbon nanotubes

Plant-based cellulose nanofibres do not pose a short-term health risk, especially short fibres, shows a study conducted in the context of National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64). But ...

A better way to build DNA scaffolds

Imagine taking strands of DNA - the material in our cells that determines how we look and function - and using it to build tiny structures that can deliver drugs to targets within the body or take electronic ...
