Researchers advance DNA nanostructure stability

Researchers at the University at Albany's RNA Institute have demonstrated a new approach to DNA nanostructure assembly that does not require magnesium. The method improves the biostability of the structures, making them more useful and reliable in a range of applications. The work appears in the journal Small this month.

"We used spectrophotometry, electron microscopy, and optical modelling to explain the mechanisms producing bright white tail feather tips of the Eurasian woodcock Scolopax rusticola. Their diffuse reflectance was approximately 30% higher than any previously measured feather. This intense reflectance is the result of incoherent light scattering from a disordered nanostructure composed of keratin and air within the barb rami"

In a conventional #Laser, light bounces back and forth through an amplifying medium placed between two mirrors. In our network lasers, we remove the mirrors and #nanostructure the amplifying medium in the form of a network so that light can take many different paths. Depending on which parts of the network we pump, light is amplified through different regions of the network, giving us different colours of lasers from the same chip.
