Aqueous Two-Phase Systems

open access: yes, 2020
During the last 60 years, aqueous two-phase systems (ATPS) have been the focus of much research. A large number of studies have been reported on the characterization of these systems and their use on separation, analytic, and biotechnological processes. On this review an overview about the ATPS fundamentals and properties is provided. Next the types of
