If you've ever sat waiting at the doctor's office to give a blood sample, you might have wished there was a way to find the same information without needles. But for all the medical breakthroughs of the 20th century, the best way to detect molecules has remained through liquids, such as blood. New research, however, could someday put a pause on pinpricks. A group of scientists announced they have created a small, portable device that can collect and detect airborne molecules -- a breakthrough that holds promise for many areas of medicine and public health.

Hydrogen boride (HB) nanosheets can inactivate viruses, bacteria, and fungi within minutes in the dark conditions. By coating surfaces with HB nanosheets, it rapidly inactivates SARS-CoV-2, influenza virus, and other pathogens. The nanosheets work by denaturing microbial proteins, offering a safe, effective, and versatile antimicrobial coating for everyday items.

Ferromagnetic semiconductors, which combine semiconductor and magnetic properties, are key to developing spin-based devices. Previously studied materials, such as (Ga,Mn)As, have Curie temperatures below room temperature, thereby limiting their practical use. Now, researchers have overcome these limitations by utilizing the step-flow growth method, achieving a record-high Curie temperature of 530 degrees K, facilitating the development of stable, room-temperature semiconductor spintronic devices.
