Biophysics & Molecular Mechanics

The physics of living systems — protein folding energy landscapes, membrane ion transport, DNA mechanical properties, molecular motor force generation, and ion channel gating dynamics.

Biophysics applies the quantitative tools of physics to biological systems, revealing the mechanical, electrical, and thermodynamic principles that govern life at the molecular scale. From the nanometer-scale forces that fold proteins into functional shapes to the piconewton steps of molecular motors walking along cytoskeletal tracks, biophysics transforms biology from descriptive to predictive.

These simulations let you explore protein folding energy landscapes, manipulate membrane transport channels, stretch DNA molecules, power molecular motors with ATP, and tune ion channel conductance — all governed by real physical equations and visualized in real time.
