Researchers create unique DNA biosensor for early stage disease detection
Missouri University of Science and Technology

Disease detection at an early stage is one of the biggest challenges biochemists and materials scientists are trying to meet by combining their expertise at Missouri S&T. The researchers used nanotechnology in biomedical diagnostics – a process called nanodiagnostics – to create a new, ultrasensitive DNA biosensor. The new sensor could potentially detect DNA-based biomarkers for early diagnosis of cancer and genetic disorders, as well as monitor patient responses to therapies.

Personalized Microrobots Swim Through Biological Barriers, Deliver Drugs to Cells
American Institute of Physics (AIP)

Biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. To be successful, they must consist of materials that can pass through the body’s immune response, swim quickly through viscous environments and penetrate tissue cells to deliver cargo. In this week’s APL Bioengineering, researchers fabricated biohybrid bacterial microswimmers by combining a genetically engineered E. coli MG1655 substrain and nanoerythrosomes, small structures made from red blood cells.

Capturing 3D microstructures in real time
Argonne National Laboratory

Argonne researchers have invented a machine-learning based algorithm for quantitatively characterizing material microstructure in three dimensions and in real time. This algorithm applies to most structural materials of interest to industry.

On Mars or Earth, biohybrid can turn carbon dioxide into new products
University of California, Berkeley

If humans ever hope to colonize Mars, the settlers will need to manufacture on-planet a huge range of organic compounds, from fuels to drugs, that are too expensive to ship from Earth.

Nanocages Trap and Separate Elusive Noble Gases
Department of Energy, Office of Science

Researchers have discovered how two-dimensional nanoscale cages trap some noble gases. These cages can trap atoms of argon, krypton, and xenon at above freezing temperatures. Noble gases are hard to trap using other methods because they condense at temperatures far below freezing.

Experiments in Mice And Human Cells Shed Light On Best Way to Deliver Nanoparticle Therapy For Cancer
Johns Hopkins Medicine

Researchers in the cancer nanomedicine community debate whether use of tiny structures, called nanoparticles, can best deliver drug therapy to tumors passively — allowing the nanoparticles to diffuse into tumors and become held in place, or actively — adding a targeted anti-cancer molecule to bind to specific cancer cell receptors and, in theory, keep the nanoparticle in the tumor longer. Now, new research on human and mouse tumors in mice by investigators at the Johns Hopkins Kimmel Cancer Center suggests the question is even more complicated.

Upconverting Nanolasers from Subwavelength Plasmons: Stability and Ultralow Powers
Department of Energy, Office of Science

Researchers have created miniature lasers that are stable and work continuously at room temperature. The lasers use arrays of nanopillars with nanoparticles that can absorb two photons of light and emit them as a single photon with higher energy. They could have applications in quantum technologies, imaging, and other areas.

New Metasurface Helps Make the Switch to Terahertz Frequencies
Department of Energy, Office of Science

Researchers are finding new applications for radiation between microwaves and infrared light. This terahertz radiation could lead to new capabilities in imaging, communications, and other areas. To expand its use, researchers need switches that work in less than a thousandth of a second, have a high contrast between “off” and “on” states, and efficiently carry electrical charges. Researchers have developed a new metasurface that does all three.
