There's gold in them thar nanoparticles, and there used to be a lot of silver, too. But much of the silver has leached away, and researchers want to know how.
Using DNA structures as scaffolds, Tim Liedl, a scientist of Ludwig-Maximilians-Universitaet (LMU) in Munich, has shown that precisely positioned gold nanoparticles can serve as efficient energy transmitters.
The idea of implantable sensors that continuously transmit information on vital values and concentrations of substances or drugs in the body has fascinated physicians and scientists for a long time. Such sensors enable the ...
Researchers at the University of Southampton have developed a new way of using nanomaterials to identify and enrich skeletal stem cells—a discovery which could eventually lead to new treatments for major bone fractures ...
When optimizing catalysis in the lab, product selectivity and conversion efficiency are primary goals for materials scientists. Efficiency and selectivity are often mutually antagonistic, where high selectivity is accompanied ...
Researchers at the University of Ottawa have debunked the decade-old myth of metals being useless in photonics—the science and technology of light—with their findings, recently published in Nature Communications, expected ...
The activity of enzymes in industrial processes, laboratories, and living beings can be remotely controlled using light. This requires their immobilization on the surface of nanoparticles and irradiation with a laser. Near-infrared ...
Much like the Jedis in Star Wars use the Force to control objects from a distance, scientists can use light or optical force to move very small particles. The inventors of this ground-breaking laser technology, known as "optical ...
Imagine seeing the world in muted shades—gray sky, gray grass. Some people with color blindness see everything this way, though most can't see specific colors. Tinted glasses can help, but they can't be used to correct ...
Hydrogen peroxide diluted in water is used as a disinfectant to treat wounds. It is widely used across the industry as an eco-friendly oxidizing agent for removing impurities from semiconductors, for waste treatment, and ...
