Defect patterns in DNA-linked crystals
Defect patterns in DNA-linked crystals.
By attaching short sequences of single-stranded DNA to nanoscale building blocks, researchers can design structures that can effectively build themselves. A Pennsylvania State University research team has shown that fluid dynamics plays a critical role for crystals that self-assemble without the pattern defects seen here.
The research was supported by the National Science Foundation through its Chemical, Bioengineering, Environmental and Transport Systems Division (grants CBET 08-29045 and CBET 11-33386).
