A new method to make very small patterns of DNA molecules on surfaces has been developed by chemists at the University of California, Davis, and Wayne State University, Detroit. The technique could allow faster and more powerful devices for DNA sequencing, biological sensors and disease diagnosis.
The technique, called nanografting, can be used to make patterns of DNA that are up to a thousand times smaller than those in commercially available microarrays, said UC Davis chemist Gang-yu Liu. Liu developed the method with Christine Chow at Wayne State University and UC Davis graduate students Maozi Liu and Nabil Amro.
"We believe these are the smallest nanostructures of DNA yet made," Liu said. They drew lines as small as 15 nanometers across by 150 nanometers long -- equivalent to eight DNA molecules across. The same method can be applied to make structures as small as two by four nanometers, or a few billionths of an inch, in size.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...
