In order to fulfill their function, biological cells need to be divided into separate reaction compartments. This is sometimes done with membranes, and sometimes without them: the spontaneous segregation of certain types of biomolecules leads to the formation of so-called condensates. Why and under which circumstances they form is currently being researched.
