Formation of Beads in Aqueous Two-Phase Systems

Spheres of agarose and other polymers are generally made in phase systems consisting of one aqueous phase and one organic phase. However, several attempts have been made to avoid the use of organic solvents, which is often hazardous to the biological function of enzymes and cells. Although the first aqueous two-phase system described in the literature was composed of starch and agar [1], such phase systems have not hitherto found any known practical use.
