Modern medicine has the desire to replace damaged tissue with newly grown tissue, such as to repair skin, bone, cartilage, or arteries. But what kinds of surfaces could be used to grow suitable tissues?
Suolong Ni, a graduate student in chemistry at Virginia Tech, has fabricated a biopolymer onto solid surfaces with a range of properties to enable the study of the effects of different surfaces on cell adhesion and tissue growth. He will present his research in the Excellence in Graduate Polymer Science Research Symposium at the 231st American Chemical Society National Meeting in Atlanta on March 26-30.
Ni has fabricated a thin film that has both smooth areas and areas where the molecules have formed a geometric or crystal-like relationship, making the surface patterned. So far he has prepared a series of surface patterns with controlled surface morphology. These surfaces may be suitable for cell adhesion studies.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
