SBP researchers advance tumor-imaging nanosystem for enhanced diagnostic imaging.
University of Utah researchers led by chemical engineering and chemistry professor Marc Porter and U surgeon and professor Courtney Scaife have developed a rapid portable screening test for liver cancer that doesn't involve sending a specimen to a blood lab and cuts the wait time for results from two weeks to two minutes. This inexpensive test can be administered wherever the patient is, which will be valuable for developing nations with little access to hospitals.
According to Dr. Emmanuel Levy and his group in the Weizmann Institute of Science's Structural Biology Department, Lego-like assemblies should have formed relatively frequently during evolution. Could this assembly method be common, or even easy to reproduce? Their answer, which was recently published in Nature, may have implications for both biological research and nanoscience.
It has not been possible to witness exactly how von Willebrand factor senses and harnesses mechanical forces in our blood vessels -- until now. A team in the Boston Children's Program in Cellular and Molecular Medicine and the HMS Department of Biological Chemistry and Molecular Pharmacology has revealed exactly how VWF stops bleeding from cuts and bruises. Cutting-edge fluorescence imaging and microfluidic tools allowed them to capture images of individual VWF molecules elongating and relaxing in response to blood flow.
Aerosol particles, says Xiaoji Xu, assistant professor of chemistry at Lehigh University, are among the many materials whose chemical and mechanical properties cannot be fully measured until scientists develop a better method of studying materials at the microscale as well as the much smaller nanoscale (1 nm is one-billionth of a meter). Xu has developed such a method and utilized it to perform noninvasive chemical imaging of a variety of materials, as well as mechanical mapping with a spatial resolution of 10 nanometers.
Now scientists at the University of Manchester have proved that storing data with a class of molecules known as single-molecule magnets is more feasible than previously thought.
The world's shortest race by distance -- a fraction of the width of a human hair -- was a huge success for scientists working at the nanoscale. It spurred interest in molecular machines and led to a surprising new discovery, reports the team that entered a nano-sized 'monster truck.' The researchers present their nanocar at the 254th National Meeting & Exposition of the American Chemical Society.
Researchers at ITMO University unveiled a new approach for printing luminescent structures based on nanoparticle ink. The unique optical properties of the ink were achieved by means of europium-doped zirconia. Particles of this material were proven to be useful for manufacturing glowing holographic coatings with a high degree of protection. Importantly, the developed approach enables the fabrication of custom holograms by means of a simple inkjet printer.
Nothing is forever, but is it possible to slow down inescapable decay? An inquiry into the delay of deterioration of quantum memory devices and formation of black holes explained with intuitive analogies from everyday life
A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used to power a range of wearable devices.
