A newly developed silicon material covered with tiny nanospikes is capable of taking out 96 percent of the virus particles unfortunate enough to touch its surface in tests. It could find a use in hospitals, science labs, and anywhere surfaces need to be as sterile as possible.
@#6,7 ... Yup, linked right there at the end of the article. That you posted. ...
Yup.
The last sentence of the article I posted is...
... The research has been published in ACS Nano.

Piercing of the Human Parainfluenza Virus by Nanostructured Surfaces
... This paper presents a comprehensive experimental and theoretical investigation into the antiviral properties of nanostructured surfaces and explains the underlying virucidal mechanism. We used reactive ion etching to fabricate silicon (Si) surfaces featuring an array of sharp nanospikes with an approximate tip diameter of 2 nm and a height of 290 nm. The nanospike surfaces exhibited a 1.5 log reduction in infectivity of human parainfluenza virus type 3 (hPIV-3) after 6 h, a substantially enhanced efficiency, compared to that of smooth Si. Theoretical modeling of the virus"nanospike interactions determined the virucidal action of the nanostructured substrata to be associated with the ability of the sharp nanofeatures to effectively penetrate the viral envelope, resulting in the loss of viral infectivity. Our research highlights the significance of the potential application of nanostructured surfaces in combating the spread of viruses and bacteria. Notably, our study provides valuable insights into the design and optimization of antiviral surfaces with a particular emphasis on the crucial role played by sharp nanofeatures in maximizing their effectiveness. ...

I know it's not quite the same situation, as this relates to viruses, but wondering if some of the same concerns with overuse of anti-bacterials will come into play.
"Strange but True: Antibacterial Products May Do More Harm Than Good Antibacterial soaps and other cleaners may actually be aiding in the development of superbacteria. [...] Unlike these traditional cleaners, antibacterial products leave surface residues, creating conditions that may foster the development of resistant bacteria, Levy notes. For example, after spraying and wiping an antibacterial cleaner over a kitchen counter, active chemicals linger behind and continue to kill bacteria, but not necessarily all of them. When a bacterial population is placed under a stressor"such as an antibacterial chemical"a small subpopulation armed with special defense mechanisms can develop. These lineages survive and reproduce as their weaker relatives perish. "What doesn't kill you makes you stronger" is the governing maxim here, as antibacterial chemicals select for bacteria that endure their presence." www.scientificamerican.com
