MBN Explorer

MesoBioNano Explorer (MBN Explorer) is a multi-purpose computer software package aimed to model molecular systems of varied level of complexity. The program is developed jointly with Prof. Andrey V. Solov'yov and his colleagues. MBN Explorer for academic institutions is distributed free of charge and includes precompiled binaries for Linux, Windows and MacOSX platforms on the MBN Explorer official website www.mbnexplorer.com.

Figure 1. Variety of molecular systems which can be simulated using MBN Explorer: encapsulated clusters, deposited nanoparticles, nanofractals, composite nanowires, proteins, biomolecules, e.g., DNA, in solution. Structure and properties of any of these objects or any of their combinations can be studied using MBN Explorer.

 

MBN Explorer allows to model molecular systems of varied level of complexity. In particular, MBN Explorer is suited to compute system's energy, to optimize molecular structure, as well as to consider the molecular and random walk dynamics. MBN Explorer allows to use a broad variety of interatomic potentials, to model different molecular systems, such as atomic clusters, fullerenes, nanotubes, polypeptides, proteins, DNA, composite systems, nanofractals, etc. On demand, MBN Explorer allows to group particles in the system into rigid fragments, thereby significantly reducing the number of dynamical degrees of freedom. Despite the universality, the computational efficiency of MBN Explorer is comparable (and in some cases even higher) than the computational efficiency of other software packages, making MBN Explorer a possible alternative to the available codes.
