Metals line up for DNA

Article Abstract:

An application of DNA molecule that stems from inorganic chemistry was used to modify DNA so that it serves as a self-assembling scaffold for one-dimensional arrays of metal ions. It was found that short artificial DNA duplex containing an array of five consecutive copper ions could interact magnetically with each other forming a self-assembled nanomagnet and these specific combinations of metal ions might be incorporated into DNA to fine-tune the magnetic properties of such devices.

Powerful curves

Article Abstract:

Microtubules help arrange the cell components and provide a transport tracks for the motor proteins. These long, thin polymers continuously grow and shrink, and the structures of two forms of the constituent protein provide clues to how this occurs.

Golden handshake

Article Abstract:

The creation of self-assembled gold nanoparticles by using the transient pairings of complementary DNA strands is reported. The three-dimensional nanoparticle arrays could be used to obtain optical and electronic materials.
