International symposium on nanoarchitectonics for mechanobiology

InterNano - Upcoming Events - July 30, 2015 - 3:45am
July 29, 2015 - Mechanobiology is a scientific field that studies the principle in sensing and generation of physical force in life. Recent studies in this field shed light on the significance of force, comparable to chemical and biochemical cues, in the regulation of biological processes. However, one unique feature in the mechanical regulation, distinct from chemical/biochemical one, is that it can directly react with the multi-layered architectures of living systems, ranging from nano-scale proteins, subcellular organelles, cells, tissues, organs to whole bodies. \"International symposium on nanoarchitectonics for mechanobiology\" stands at this viewpoint with a special attention to researches on novel molecules and materials to dissect and control mechano-nanoarchitectonics of life. Presentations in the symposium are made by a wide variety of speakers from material science, sensors and actuators, mechanochemistry, interfacial sciences, and of course biology. We hope that all the participants will obtain fresh inspiration from the lectures. Tsukuba, Japan

Nanoparticles Accelerate and Improve Healing of Burn Wounds

National Nanomanufacturing Network - July 29, 2015 - 12:56pm
Michael Berger, NanowerkNAC-SNO nanoparticles clinically accelerate burn wound healing. (©Journal of Drugs in Dermatology) Skin thermal burns are a complex and major source of morbidity, mortality and healthcare expenditure in the United States, with 486,000 patients treated for burn injury each year. Given the range of causes, from fire associated injury to water scalding, patients often present with multiple and complex burns – wounds that often worsen and expand over the first few days do to the associated underlying inflammation and injury. "Though the impact of these injuries is large, our current treatment armament falls short, with gold standard treatments lacking evidence to support their use, or even worse, may even delay wound healing as was recently elucidated with silver sulfadiazine," Dr. Adam Friedman, Associate Professor of Dermatology and Director of Translational Research at the George Washington School of Medicine and Health Sciences, tells Nanowerk. To address this gap, Friedman and colleagues at the Albert Einstein College of Medicine utilized a unique nanotechnology that can both release the potent biomolecule nitric oxide (NO) over time, as well as facilitate nitrosation, the addition of an NO group to a biological molecule, which is central many of NO’s activity. The team reported their findings in Journal of Drugs in Dermatology ("N-acetylcysteine S-nitrosothiol Nanoparticles Prevent Wound Expansion and Accelerate Wound Closure in a Murine Burn Model"). "The role of nitric oxide in wound healing is well established through all three phases," says Friedman. "Both NO itself and the act of nitrosation are exceedingly important in the transition from the inflammatory phase to the proliferative phase of wound healing. Therefore, we created a system that can do both." The scientists evaluated a previously described S-nitroso-N-acetyl cysteine containing hydrogel-based nanoparticle platform (NAC-SNO-np) on in vivo burn wound closure, expansion and inflammation in a multi burn model. Burn wound expansion in the NAC-SNO-np in coconut oil treated group was significantly attenuated compared to untreated control, coconut oil, and control-np groups. The clinically observed acceleration of wound healing was matched with the histologic evaluation of the burn wounds, with the NAC-SNO-np treated groups showing less persistent inflammation, more maturation, and healthier new tissue as compared to the other groups over time. While still in its infancy, Friedman believes this technology will be brought from bench to bedside as it has been licensed by the company Nano Biomed Inc. "The reality is many impressive technologies fail to launch because the business and financial element aren't nurtured," says Friedman. "Nanotechnology in general has extraordinary potential to change the face of medicine, but it is unfortunately not enough to just have a good scientific basis or data." "Along this theme, it is in fact only through the unique structure of the nanomaterial herein investigated that allows for the generation of nitric oxide and confers the nitrosation capacity offered by the NAC-SNO-np," he concludes.

Nano Dimension

National Nanomanufacturing Network - July 29, 2015 - 10:02am
DirectoryWe all wish that developing multi-layer professional PCBs was faster and more flexible. That's why we're making a 3D PCB printer and a suite of nano-technology inks specifically for PCB professionals. The Nano Dimension PCB printer is a highly accurate and versatile inkjet deposition system for printing multi-layer circuit boards. The innovative hardware, dedicated nano-inks and novel software bring new possibilities to a wide range of R&D, prototyping and custom manufacturing projects. Our highly conductive silver nano-inks are also available separately. Nano Dimension has two fully equipped laboratories. One laboratory is dedicated to the research and production of conductive silver nano-particle inks. The second laboratory is focused on innovative dielectric nano-inks. The labs are focused primarily on nano-silver and nano-polymers for our 3D PCB printer but we can help you with your advanced ink requirements, so feel free to get in touch. Nano Dimension’s wet-chemistry approach to making silver nano-particles starts with a silver precursor raw material. The patented process, licensed from the Hebrew University, is highly efficient and very clean. We can reliably extract 10-100+ nano-meter sized particles of pure silver. Our labs can control the size, shape and dispersion of the silver nano-particles in accordance with your printing requirements. We can also formulate inks for a variety of substrates and printing profiles. Our high-performance silver nano-particle ink for inkjet printers is available for purchase/testing by industry partners seeking high conductivity for RFID, antenna, OLED and other applications.
