The application’s greatest appeal

Software for calculating the free energy of molecular aggregate systems. Combines molecular dynamics and the theory of solutions in the energy representation method, enabling rapid, high-precision calculation of the free energy of substances binding to molecular aggregates. The software supports normal solutions, and it can also determine the solubility of a wide range of solvent species such as supercritical fluids and ionic fluids. Bonding strengths and sites for materials bonding to micelles, lipid membranes, and proteins can also be evaluated.
