Surfaces can be designed with antiviral properties to mitigate COVID-19

540529

Sumary of Surfaces can be designed with antiviral properties to mitigate COVID-19:

  • An optimally designed surface will make a viral load decay rapidly, rendering it less likely to contribute to the spread of viruses..
  • “In terms of physics, the solid-liquid interfacial energy is enhanced by a combination of our proposed surface engineering and augmenting the disjoining pressure within the residual thin film, which will speed drying of the thin film,”.
  • The researchers were surprised to discover that the combination of a surface’s wettability and its physical texture determine its antiviral properties..
  • While previous studies reported antibacterial effects by designing superhydrophobic (repels water) surfaces, their work indicates antiviral surface design can be achieved by surface hydrophilicity (attracts water)..
  • The researchers discovered that surfaces with taller and closely packed pillars, with a contact angle of around 60 degrees, show the strongest antiviral effect or shortest drying time…
