Recent results show that the time it takes to produce such objects can be cut from days to minutes, with yields near 100 percent. (Credit: Copyright Dietz Lab, TU Muenchen)

Lowering Barriers to DNA-Based Nanomanufacturing

Dec. 13, 2012 — Two major barriers to the advancement of DNA nanotechnology beyond the research lab have been knocked down. This emerging technology employs DNA as a programmable building material for self-assembled, nanometer-scale structures. Many practical applications have been envisioned, and researchers recently demonstrated a synthetic membrane channel made from DNA. Until now, however, design processes were hobbled by a lack of structural feedback. Assembly was slow and often of poor quality.

Now researchers led by Prof. Hendrik Dietz of the Technische Universitaet Muenchen (TUM) have removed these obstacles.
