Before revision: The APBS software was developed to solve the equations of continuum electrostatics for large biomolecular assemblages.
After revision: Virtual reality is a powerful tool with the ability to immerse a user within a completely external environment. This immersion is particularly useful when visualizing and analyzing interactions between URLanic molecules, molecular URLanic complexes, and biomolecular systems such as redox proteins and enzymes. A common tool used in the biomedical community to analyze such interactions is the APBS software, which was developed to solve the equations of continuum electrostatics for large biomolecular assemblages.
