Turmeric has a long history of usage in traditional medicine in India and China. Ancient Indians have known the medicinal properties of turmeric - i.e. curcumin - for several millennia. Researchers have now investigated the antibacterial effects of curcumin loaded into halloysite nanotubes and found that this nanoformulation drastically increased the life expectancy of nematodes infected by pathogenic bacteria. The most interesting...

The recent interest of nanotechnology researchers in liquid metals is based on the properties that differentiate them from common liquids such as water or organics. In addition to their chemical reactivity, the electronic behavior of these liquids, combined with the strong interatomic interactions throughout the bulk, lead to liquids with high densities, thermal and electrical conductivities, and optical reflectivity (over...

Recently, the investigation of ternary layered compounds with 2D features has emerged. Compared to 2D elements and binary compounds, ternary layered compounds possess more tunability for physical and chemical properties due to more element species. Therefore, exploring the preparation methods and special properties of 2D ternary compounds is of great significance for enriching the 2D material library and expanding the application...

Electronic skin (e-skin) technology will give prosthetics and soft robotics a finer sense of touch, of what's hard and soft, hot and cold, smooth and rough. Researchers have now demonstrated a soft robotic hand integrated with four tactile force sensors and one temperature sensor to give it similar sensitivity to a human hand. By integrating an e-skin, the tactile pressure to grab an object and the friction movement of an...

Electronic transitions between confined states within a quantum well are widely used in optoelectronics. Familiar examples include quantum cascade lasers and quantum well infrared photodetectors, which can operate in a wide range of wavelengths, from the far- to near-infrared. There is growing interest in studying this phenomenon because it may enable novel devices such as polariton lasers and because the physics of ISB polaritons...

When nanoparticles enter the blood stream or other biological fluids, they are quickly surrounded by a layer of proteins. This so-called protein corona on the nanoparticles hinders interactions between the targeting ligands on the nanoparticles and their binding partners on the cells' surface. Different individuals may have a personalized protein corona owing to their distinct type, severity and period of disease, heterogeneity,...

A critical challenge in gene therapy is the safe and effective delivery of genetic materials across cell membranes into target cells. Although viral systems have been the most effective method for delivering genetic matter into cells, they pose significant safety problems. Demonstrating a novel alternative delivery vector, researchers have developed a facile one-pot strategy to encapsulate plasmid DNA into nanoscale metal-organic...
