DNA devices perform bio-analytical chemistry inside live cells

Some biochemistry laboratories fashion proteins into complex shapes, constructing the DNA nanotechnological equivalent of Baroque or Rococo architecture. Yamuna Krishnan, however, prefers structurally minimalist devices.

A new way to make higher quality bilayer graphene

(Phys.org)—A team of researchers with members from institutions in the U.S., Korea and China has developed a new way to make bilayer graphene that is higher in quality than that produced through any other known process. ...

Researchers build nanoscale autonomous walking machine from DNA

Researchers at The University of Texas at Austin have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer ...

Cells get noisy in crowded environments

Bacteria are incredibly small, yet pack an enormous diversity of different molecules such as DNA, mRNA and proteins. Chemists from Radboud University Nijmegen, Eindhoven and Paris now show for the first time that random variations ...

Nanotechnology inspires next-generation dental materials

Have a cavity? Ask your dentist about filling it with a mixture of nanoparticles including silica and zirconia. These white fillings (known as nano-composite resins) resemble teeth better than their metal alternatives and ...

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 environments, ...

Scientists convert microbubbles to nanoparticles

Biomedical researchers led by Dr. Gang Zheng at Princess Margaret Cancer Centre have successfully converted microbubble technology already used in diagnostic imaging into nanoparticles that stay trapped in tumours to potentially ...
