Controlled growth of DNA nanomaterials opens new applications in nanoelectronics
Nanowerk News) DNA-based nanomaterials are
key precursors for the bottom- up fabrication of
a range of high-performance nanoscale devices
such as biosensors and nanoelectronics because
of their ability to self-assemble into well-defined
structures. However, the lack of control
encountered during the deposition of these
nanostructures on surfaces has hampered their
application in practical devices.
Sung Ha Park, Yonghan Roh and colleagues
from Sungkyunkwan University and the
Samsung Advanced Institute of Technology in
Korea have now developed a surface-promoted
method that allows for the precise control of
DNA crystal growth on silica substrates
("Coverage Control of DNA Crystals Grown by
Silica Assistance" ).
