Researchers are developing a new imaging technique involving nanoparticles suspended in liquid to form 'nanojuice' that patients would drink. Upon reaching the small intestine, doctors would strike the nanoparticles with a harmless laser light, providing an unparalleled, non-invasive, real-time view of the organ.
Researchers have developed a paint for use in coatings and packaging that changes color when exposed to high temperatures, delivering a visual warning to people handling material or equipment with the potential to malfunction, explode, or cause burns when overheated.
Having perfected an isotope labeling method allowing extremely sensitive detection of carbon nanotubes in living organisms, researchers have looked at what happens to nanotubes after one year inside an animal.
Nanosupply provides an easy and safe platform to source and share advanced materials for research and education. Their mission is to encourage collaboration, help researchers and science educators save time and money, and decrease research originated waste.
Researchers have developed a microfluidic technique for fabricating a new class of metal-organic framework (MOF) membranes inside hollow polymer fibers that are just a few hundred microns in diameter. The new fabrication process, believed to be the first to grow MOF membranes inside hollow fibers, could potentially change the way large-scale energy-intensive chemical separations are done.
Nonlinear optical materials are widely used in laser systems. However, high light intensity and long propagation are required to produce strong nonlinear optical effects. Researchers created metamaterials with a million times stronger nonlinear optical response, compared to the traditional nonlinear materials, and demonstrated frequency conversion in films 100 times thinner than human hair using light intensity comparable to that of a laser pointer.
