@MattWoodwardUK Hi Matt, please follow would love to share something via DM

25/25 If the virus is on your hands you can pass it on by shaking someone’s else hand. Kisses, well, that's pretty obvious…It comes without saying that if someone sneezes right in your face you are kind of stuffed. Part 2 about soap coming next (25 post limit reached)!

[Palli Thordarson @PalliThordarson]

24/25 And now the virus is dangerously close to the airways and the mucus type membranes in and around your mouth and eyes. So the virus can get in…and voila! You are infected (that is, unless your immune system kills the virus).

[Palli Thordarson @PalliThordarson]

23/25 So when you touch say a steel surface with a virus particle on it, it will stick to your skin and hence get transferred onto your hands. But you are not (yet) infected. If you touch your face though, the virus can get transferred from your hands and on to your face.

[Palli Thordarson @PalliThordarson]

22/25 The skin is an ideal surface for a virus! It is “organic” and the proteins and fatty acids in the dead cells on the surface interact with the virus through both hydrogen bonds and the “fat-like” hydrophilic interactions.

[Palli Thordarson @PalliThordarson]

21/25 For how long does the virus stay active? It depends. The SARS-CoV-2 coronavirus is thought to stay active on favourable surfaces for hours, possibly a day. Moisture (“dissolves”), sun light (UV light) and heat (molecular motions) all make the virus less stable.

[Palli Thordarson @PalliThordarson]

20/25 In contrast steel, porcelain or teflon do not form a lot of hydrogen bond with the virus. So the virus is not strongly bound to these surfaces. The virus is quite stable on these surface whereas it doesn’t stay active for as long on say fabric or wood.

[Palli Thordarson @PalliThordarson]

19/25 So why are surfaces different? The virus is held together by a combination of hydrogen bonds (like those in water) and what we call hydrophilic or “fat-like” interactions. The surface of fibres or wood for instance can form a lot of hydrogen bonds with the virus.

[Palli Thordarson @PalliThordarson]

18/25 Contrast this with steel, porcelain and at least some plastics, e.g. teflon. The surface structure also matter – the flatter the surface the less the virus will “stick” to the surface. Rougher surfaces can actually pull the virus apart.

[Palli Thordarson @PalliThordarson]

17/25 Now it is time to introduce a powerful supramolecular chemistry concept that effectively says: similar molecules appear to interact more strongly with each other than dissimilar ones. Wood, fabric and not to mention skin interact fairly strongly with viruses.

[Palli Thordarson @PalliThordarson]

16/25 These tiny droplets end on surfaces and often dry out quickly. But the viruses are still active! What happens next is all about supramolecular chemistry and how self-assembled nanoparticles (like the viruses) interact with their environment!

[Palli Thordarson @PalliThordarson]

15/25 When you cough, or especially when you sneeze, tiny droplets from the airways can fly up to 10 meters (30 ft)! The larger ones are thought to be main coronavirus carriers and they can go at least 2 m (7 ft). Thus – cover your coughs & sneezes people!

[Palli Thordarson @PalliThordarson]

14/25 All those new viruses eventually overwhelm the cell and it dies/explodes releasing viruses which then go on to infect more cells. In the lungs, some of these viruses end up in the airways and the mucous membranes surrounding these.

[Palli Thordarson @PalliThordarson]

13/25 These new RNA and protein molecules, self-assemble with lipids (usually readily present in the cell) to form new copies of the virus. That is, the virus does not photocopy itself, it makes copies of the building blocks which then self-assemble into new viruses!
