New material neutralizes 96-percent of virus cells using nanospikes
Researchers at Australia’s Royal Melbourne Institute of Technology (RMIT) have combined brute force with high tech manufacturing to create a new silicon material for hospitals, laboratories and other potentially sensitive environments. And although it might look and feel like a flat, black mirror to humans, the thin layering actually functions as a thorny deathtrap for pathogens. As recently detailed in the journal ACS Nano, the interdisciplinary team spent over two years developing the novel material, which is smooth to the human touch. At a microscopic level, however, the silicon surface is covered in “nanospikes” so small and sharp that they can impale individual cells. In lab tests, 96-percent of all hPIV-3 virus cells that came into contact with the material’s miniscule needles either tore apart, or came away so badly damaged that they couldn’t replicate and create their usual infections like pneumonia, croup, and bronchitis. With no external assistance, these eradication levels could be accomplished within six hours. A virus cell on the nano spiked silicon surface, magnified 65,000 times. After 6 hours it has …
