Injectable Nano-Network Controls Blood Sugar in Diabetics for Days at a Time

In a promising development for diabetes treatment, researchers have developed a network of nanoscale particles that can be injected into the body and release insulin when blood-sugar levels rise, maintaining normal blood sugar levels for more than a week in animal-based laboratory tests. The work was done by researchers at North Carolina State University, the…

Researchers ‘Nanoweld’ by Applying Light to Aligned Nanorods in Solid Materials

Researchers from North Carolina State University have developed a way to melt or “weld” specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials. Physicists Jason Bochinski and Laura Clarke, with materials scientist…

Study Improves Understanding of Surface Molecules in Controlling Size of Gold Nanoparticles

North Carolina State University researchers have shown that the “bulkiness” of molecules commonly used in the creation of gold nanoparticles actually dictates the size of the nanoparticles – with larger so-called ligands resulting in smaller nanoparticles. The research team also found that each type of ligand produces nanoparticles in a particular array of discrete sizes.
