"In this case, however, viruses are an order of magnitude smaller than bacteria so the needles must be correspondingly smaller if they are to have any effect on them."
And animal cells are an order of magnitude larger than bacterial cells, so I wouldn't worry about the spikes on my skin
- adrian_b 2y agoThe reason why you should not worry about the spikes on your skin is because the surface of your skin is made by dead cells. Otherwise, the thickness of the cellular membranes is small in comparison with virus sizes and spike sizes, so these spikes should rip them apart too. A mosquito is many orders of magnitude smaller than you, but you should still worry when it comes in contact with your skin, because it is not your size that matters, but only the thickness of your skin.
