Researchers at Rice University have identified a novel, second level of fluorescence by carbon nanotubes. The Rice University team discovered that single-walled nanotubes emit a delayed secondary fluorescence when triggered by a multistep process in a solution with dye molecules and dissolved oxygen. Potential applications for the findings include optoelectronics and solar energy developments.

Scientists at Washington State University have used human white blood cell membranes to carry two drugs, an antibiotic and an anti-inflammatory, directly to infected lungs in mice. The nano-sized drug delivery method successfully treated both the bacterial growth and inflammation in the mice's lungs. The study shows a potential new strategy for treating infectious diseases, including COVID-19.

Researchers at Columbia University report that they have achieved plasmonically active graphene with record-high charge density without an external gate. They accomplished this by exploiting novel interlayer charge transfer with a two-dimensional (2D) electron-acceptor known as α-RuCl3. α-RuCl3 is unique among nanomaterials because it has an exceptionally high work function even when it is exfoliated down to a one- or few-atom-thick 2D layers.

Researchers at Penn State are beginning to understand the behavior of so-called "active" particles, which, if controlled, has potential implications for smart 3D printing and engineered drug delivery systems. The particles – which can be biological but, in this case, are cylindrical platinum-gold nanorods smaller than a red blood cell – flow in a fluid through a micro-channel into a tapered nozzle. Once collected there, they can be used in additive manufacturing to 3D-print objects or to deliver therapeutics directly to cells.

Researchers at Drexel University have developed antennas that are so thin they can be sprayed into place and robust enough they can provide a strong signal at bandwidths that will be used by fifth-generation (5G) mobile devices. The new antennas, which are made from a two-dimensional material called MXene, are already performing nearly as well as the copper antennas found in most mobile devices on the market today, but with the benefit of being just a fraction of their thickness and weight.
