Researchers have created a new type of molecular motor made of DNA and demonstrated its potential by using it to transport a nanoparticle along the length of a carbon nanotube. The design was inspired by natural biological motors that have evolved to perform specific tasks critical to the function of cells, said Jong Hyun Choi, a Purdue University assistant professor of mechanical engineering. Whereas biological motors are made of protein, researchers are trying to create synthetic...

Researchers find nanostructures made of DNA strands can encapsulate, release small-molecule drugs Nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, McGill University researchers report in a new study. The research, published online Sept. 1 in Nature Chemistry, marks a step toward the use of biological nanostructures to deliver drugs to diseased cells in patients. The findings could also open up new...

In a new discovery that represents a major step in solving a critical design challenge, Arizona State University Professor Hao Yan has led a research team to produce a wide variety of 2-D and 3-D structures that push the boundaries of the burgeoning field of DNA nanotechnology. The field of DNA nanotechnology utilizes nature's design rules and the chemical properties of DNA to self-assemble into an increasingly complex menagerie of molecules for biomedical and electronic applications. Some...

Lowering Barriers To DNA-based Nanomanufacturing
2012-12-14 11:12:22

Technische Universitaet Muenchen 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...

'Mechanically Active' DNA Material Designed
2012-10-23 07:46:47

Researchers at UC Santa Barbara designed a 'smart' material made of DNA that responds with movement when stimulated Artificial muscles and self-propelled goo may be the stuff of Hollywood fiction, but for UC Santa Barbara scientists Omar Saleh and Deborah Fygenson, the reality of it is not that far away. By blending their areas of expertise, the pair have created a dynamic gel made of DNA that mechanically responds to stimuli in much the same way that cells do. The results of their...

DNA Code Shapes Gold Nanoparticles
2012-08-08 16:01:32

DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA´s code can similarly shape metallic structures. The team found that DNA segments can direct the shape of gold nanoparticles — tiny gold crystals that have many applications in medicine, electronics and catalysis. Led by Yi Lu, the Schenck Professor of Chemistry at the U. of I., the team published its surprising findings in the journal Angewandte...

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a method for building complex nanostructures out of short synthetic strands of DNA. Called single-stranded tiles (SSTs), these interlocking DNA "building blocks," akin to Legos®, can be programmed to assemble themselves into precisely designed shapes, such as letters and emoticons. Further development of the technology could enable the creation of new nanoscale devices, such as...

New York University scientists have developed artificial structures that can self-replicate, a process that has the potential to yield new types of materials. The work, conducted by researchers in NYU's Departments of Chemistry and Physics and its Center for Soft Matter Research, appears in the latest issue of the journal Nature. In the natural world, self-replication is ubiquitous in all living entities, but artificial self-replication has been elusive. The discovery in Nature reports the...
