• "New functions of hydrogen boride sheets" Published on May 9, 2025, 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.
