(Nanowerk News) The world-altering coronavirus behind the COVID-19 pandemic is thought to be just 60 nanometres to 120 nanometres in size (read more: Journal of Advanced Research, “COVID-19 infection: Origin, transmission, and characteristics of human coronaviruses”). This is so mind bogglingly small that you could fit more than 400 of these virus particles into the width of a single hair on your head. In fact, coronaviruses are so small that we cant see them with normal microscopes and require much fancier electron microscopes to study them. How can we battle a foe so minuscule that we cannot see it?
