Droplet nucleus

Droplet nuclei are aerosols formed from the evaporation of respiratory droplets.[1] They are generally smaller than 5 μm in diameter. Droplet nuclei are formed by the "dried residua of larger respiratory droplets".[2] These particles are "the vehicle for airborne respiratory disease transmission, which are the dried-out residual of droplets possibly containing infectious pathogens".[3] Diseases such as tuberculous and COVID-19 can be transmitted via droplet nuclei.[2][4]
