Engineers at MIT have developed a novel platform for the controlled delivery of drugs and nutrients to human cells. Their simple approach creates small capsules containing thousands of nanosized droplets loaded with a drug or other active ingredient. The ingredient-loaded droplets can easily pass through cell walls, are exceptionally stable, and can carry a large amount of active ingredient for their size.
Researchers at Vanderbilt University have developed the first-ever optical nanotweezers that can trap and manipulate nanometer-scale objects. The nanotweezers can also sort objects based on their size, an approach that is important when looking for extracellular vesicles secreted by cells that can cause cancers to metastasize. Other applications of the nanotweezers include detecting pathogens and researching proteins that contribute to conditions associated with neurodegenerative diseases.

Scientists at Oak Ridge National Laboratory have discovered a cost-effective way to significantly improve the mechanical performance of common polymer nanocomposite materials. The discovery could lead to stronger, more durable materials for applications ranging from biomedical devices to automobile tires.

Scientists at Clemson University have developed a new type of battery electrode made of silicon that can store more energy than traditional graphite electrodes in lithium-ion batteries. The new electrode uses layers of a carbon nanotube material, called Buckypaper, with silicon nanoparticles sandwiched between them.

Using a device small enough to fit on the head of a pin, researchers at the University of Illinois at Urbana-Champaign have gained new knowledge about the properties of polymer fibers at the nanoscale. This knowledge could inform the design and manufacture of products made up of random networks of filaments, such as robust filters designed to block foreign particles from entering our lungs.

Researchers at Cornell University have used an ultrathin graphene “sandwich” to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes in magnetic fields that might otherwise get lost within a larger magnetic background.
