Researchers at Washington University in St. Louis have developed a microneedle patch that can help detect small amounts of antibodies in interstitial fluid. The researchers used fluorescence nanolabels to detect protein biomarkers present in small amounts in interstitial fluid. The signal from the target biomarkers in samples was approximately 1,400 times brighter than that from conventional fluorescent labels.
By embedding carbon nanotubes in the fibers of a bandage, scientists at the University of Rhode Island have created a continuous, noninvasive way to detect and monitor an infection in a wound. The "smart bandage" can be monitored by a miniaturized wearable device, which wirelessly detects the signal from the carbon nanotubes in the bandage. The signal can then be transmitted to a smartphone-type device that automatically alerts the patient or a health care provider.

Scientists at the National Institute of Standards and Technology (NIST) have miniaturized the optical components required to cool atoms down to a few thousandths of a degree above absolute zero. Light is launched from an optical integrated circuit using a device called an extreme mode converter. The converter enlarges the narrow laser beam, which then strikes an ultrathin film known as a metasurface, which is studded with tiny nanopillars that act to further widen the laser beam. The dramatic widening allows the beam to interact with and cool a large collection of atoms.

Researchers from Caltech, California State University, Northridge, and the National Institute for Materials Science in Tsukuba, Japan, have found that magic-angle twisted bilayer graphene has unexpected topological quantum phases. The researchers used scanning tunneling microscopy to directly image twisted bilayer graphene with atomic resolution and found that the strong interactions between electrons in twisted bilayer graphene enable the emergence of these topological phases without the need for a strong magnetic field.

Typically, bioelectronics are created through a "top-down" approach, with the electronics already put together and made smaller to fit with a biological system. But researchers from the University of Chicago and Northwestern University have taken a "bottom-up" approach, in which small building blocks, called micelles, come together to form carbon-based bioelectronics. The small micelles come together to form very thin sheets that are nanoporous – covered with extremely tiny holes – and allow for more flexibility.

When sheets of two-dimensional nanomaterials, such as graphene, are stacked on top of each other, tiny gaps form between the sheets that have a wide variety of potential uses. Now, a team of researchers from Brown University has found a way to orient those gaps, called nanochannels, in a way that makes them more useful for filtering water and other liquids of nanoscale contaminants.
