Nanotechnology offers solutions to pressing global issues, but they also have the potential to lead to unexpected risks and unintended consequences. A newly released book, Nanotechnology Environmental Health and Safety: Risk, Regulation and Management, offers insights into how these new technologies may be applied to build a sustainable future and provides practical strategies for identifying and mitigating the potential risks that accompany emerging nanotechnology.
Researchers have created an imaging technology more powerful than anything that has existed before, and is fast enough to observe life processes as they actually happen at the molecular level. This will allow creation of improved biosensors to study everything from nerve impulses to cancer metastasis as it occurs
In preclinical tests, artificial platelets, called 'hemostatic nanoparticles', when injected after blast trauma increased survival rates to 95 percent from 60 percent, and showed no signs of interfering with healing or causing other complications weeks afterward.
A research collaboration between Brigham and Women's Hospital and Dana-Farber Cancer Institute has utilized nanomedicine technologies to develop a drug-delivery system that can precisely target and attack cancer cells in the bone, as well as increase bone strength and volume to prevent bone cancer progression.
Researchers have developed a novel strategy to produce single-walled carbon nanotubes with specific chirality by applying a new family of catalysts, which has great applications and influence in nanoelectornics and related fields.
Scientists have discovered that molybdenum trioxide nanoparticles oxidize sulfite to sulfate in liver cells in analogy to the enzyme sulfite oxidase. The functionalized Molybdenum trioxide nanoparticles can cross the cellular membrane and accumulate at the mitochondria, where they can recover the activity of sulfite oxidase.
Physicists have solved a mystery that has puzzled scientists for half a century. They show with the help of powerful microscopes that the distance between graphite oxide layers gradually increases when water molecules are added.
