Cambridge, MA: The nanotechnology research space is rapidly growing, with vast implications for the healthcare, consumer electronics, surveillance, and defense industries. However, a major limitation to this research is the ability to create particles that vary in shape and function on a micrometer or nanometer scale.

To overcome these limitations, chemical engineers at Johns Hopkins University have developed self-assembling particles that are inspired by origami, the traditional Japanese art of folding paper into complex three-dimensional shapes. A new article in JoVE (Journal of Visualized Experiments) demonstrates the fabrication and folding of these particles.

"In this video-article, we take the idea of folding up particles and demonstrate the technology in two applications. In the first application, the particles seal up because of glue like material at the edges. In the second part, we talk about structures that reconfigure in response to a stimulus," said author Dr. David Gracias of Johns Hopkins University in Baltimore, Maryland.

Dr. Gracias uses a process called photolithography to etch structural designs and flexible hinges on to a 2-D surface. When these complex patterns are exposed to the correct environmental pressures, they can be manipulated to fold and seal or open and close. This fabrication process also allows crucial structural patterns to be printed on 3-D particles, as Dr. Gracias explains: "Patterns are required for electronic circuits, and we allow patterns to be used in 3-D. The applications are numerous, ranging from drug delivery to mechanical sensing, bio-sensing technologies applicable to threat detection, surveillance, and in non-invasive surgery or biopsies."

The authors believe that the applications of this technology are far reaching, and that video publication in JoVE will expedite its adoption by other scientists. "We have developed a new platform, like welding, and we hope that publishing the video will make it more likely for others to use this platform," Dr. Gracias explains. He continues, "One of the concerns with chemistry is that most chemists work with models which cannot be seen. Animation and videos published in JoVE will make these models much easier to understand."

This video article is published in JoVE Chemistry, the newest section of JoVE that was launched in February 2013. "This article really underscores why we chose to open JoVE Chemistry," said Associate Editor Rachelle Baker about Dr. Gracias' article. She continues, "Not only is chemistry a fundamental science but it is a meeting point for interdisciplinary research with bioengineering and physics as well. A video protocol that can enable 2D patterning onto 3D particles of various sizes will be widely applicable to other studies in various disciplines."

A cooler way to protect silicon surfaces

2013-02-13
CAMBRIDGE, MA -- Silicon, the material of high-tech devices from computer chips to solar cells, requires a surface coating before use in these applications. The coating "passivates" the material, tying up loose atomic bonds to prevent oxidation that would ruin its electrical properties. But this passivation process consumes a lot of heat and energy, making it costly and limiting the kinds of materials that can be added to the devices. Now a team of MIT researchers has found a way to passivate silicon at room temperature, which could be a significant boon to solar-cell ...

Protein central to cancer stem cell formation provides new potential target

Protein central to cancer stem cell formation provides new potential target
2013-02-13
HOUSTON - Researchers have identified a pivotal protein in a cellular transformation that makes a cancer cell more resistant to treatment and more capable of growing and spreading, making it an inviting new target for drug development. Additionally, the international team led by scientists at The University of Texas MD Anderson Cancer Center found the cancer drug sunitinib potentially has a new role in treating triple-negative, claudin-low breast cancer, a particularly resistant version of a type of cancer that is already difficult to treat. "We found that FOXC2 lies ...

NASA's Chandra suggests rare explosion created our galaxy's youngest black hole

NASAs Chandra suggests rare explosion created our galaxys youngest black hole
2013-02-13
New data from NASA's Chandra X-ray Observatory suggest a highly distorted supernova remnant may contain the most recent black hole formed in the Milky Way galaxy. The remnant appears to be the product of a rare explosion in which matter is ejected at high speeds along the poles of a rotating star. The remnant, called W49B, is about a thousand years old as seen from Earth and located about 26,000 light-years away. "W49B is the first of its kind to be discovered in the galaxy," said Laura Lopez, who led the study at the Massachusetts Institute of Technology. "It appears ...

By guessing, clinicians may miss 3/4 of alcohol problems

2013-02-13
SAN ANTONIO, Texas (Feb. 13, 2013) — By relying on hunches rather than posing a few screening questions, primary care clinicians may be missing three-fourths of the alcohol problems in their patients, a newly released analysis shows. "It's often off the radar — people come in for hypertension and are not asked how much they drink," said study co-author Barbara J. Turner, M.D., M.S.Ed., M.A., M.A.C.P., of UT Medicine San Antonio. Primary care offices typically don't have good systems to administer questionnaires to screen for certain problems, including alcohol consumption, ...

Tube versus IV feeding in malnourished pediatric cancer patients

2013-02-13
About 60 percent of pediatric cancer patients experience malnourishment during treatment. At that point, patients and families have a choice: tube feeding or IV nutrition supplement. Which would you choose? A study published this week in the Journal of Pediatric Oncology Nursing shows that families' perceptions, especially of the discomfort of tube feeding, leads to choosing IV over tube – despite the fact that tube feeding is usually the better choice, associated with better gut function and lower rates of infection. "Despite the benefits of tube feeding, we found a ...

Key molecule suppresses growth of cancerous liver tumors, Mayo study finds

2013-02-13
ROCHESTER, Minn. -- A molecule already implicated in a number of diverse cellular functions can suppress the growth of tumors in the liver, a Mayo Clinic Cancer Center study has found. Its name is IQGAP1, and when the molecule is active in the cells that surround a tumor cell, this "tumor microenvironment" becomes less hospitable to cancer growth. When the molecule is deficient, cancer thrives. Results of the study appear in the Journal of Clinical Investigation. The findings give new insight into cancer metastasis, the ability of a tumor to spread from its primary site ...

Southwest regional warming likely cause of pinyon pine cone decline, says CU study

Southwest regional warming likely cause of pinyon pine cone decline, says CU study
2013-02-13
Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study. The new study showed that pinyon pine seed cone production declined by an average of about 40 percent at nine study sites in New Mexico and northwestern Oklahoma over the past four decades, said CU-Boulder doctoral student Miranda Redmond, who led the study. The biggest declines in pinyon pine seed cone reproduction were at the ...
