DNA as invisible ink can reversibly hide patterns

(PhysOrg.com) -- While most people know of DNA as the building blocks of life, these large molecules also have potential applications in areas such as biosensing, nanoparticle assembly, and building supramolecular structures. ...

A flash of light turns graphene into a biosensor

(PhysOrg.com) -- Biomedical researchers suspect graphene, a novel nanomaterial made of sheets of single carbon atoms, would be useful in a variety of applications. But no one had studied the interaction between graphene and ...

Models begin to unravel how single DNA strands combine

(PhysOrg.com) -- Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double ...
