Biological condensates
Biological condensates or bio-condensates or protein droplets are membrane-less organelles formed as a result of proteins undergoing liquid-liquid phase separation or demixing. This is an important phenomenon which was recently discovered and is now not only considered critical for normal biological functions but also linked to pathological conditions like neurodegenerative diseases and cancer. Considering the importance of this natural phenomenon, I have compiled a list of sources providing videos or movies of the formation of biological condensates or describing this phenomenon in detail:
