With chemical modification, stable RNA nanoparticles go 3-D

(PhysOrg.com) -- For years, RNA has seemed an elusive tool in nanotechnology research -- easily manipulated into a variety of structures, yet susceptible to quick destruction when confronted with a commonly found enzyme.

Spiders at the nanoscale: Molecules that behave like robots

A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular "robot" made out of DNA to ...

Nanoparticles may cause DNA damage across a cellular barrier

(PhysOrg.com) -- Scientists have shown in the laboratory that metal nanoparticles damaged the DNA in cells on the other side of a cellular barrier. The research, by the University of Bristol, is published online this week ...

DNA molecules can detect pathogens, deliver drugs

(PhysOrg.com) -- First, Cornell researchers created DNA "bar codes" -- strands of the genetic material that quickly identify the presence of different molecules by fluorescing. Now, they have created new DNA molecules that ...
