Turbulence has traditionally been considered impossible in nanoscale biological environments due to strong viscous damping and low Reynolds numbers. Here I introduce the concept of nano-turbulence: a novel, coherence-driven, hydrodynamic-like regime emerging from quantum π-field dynamics within biomolecules, particularly proteins. Building on the bio-quantum framework of Quantum π in Biomolecular Dynamics, I show that proteins behave as nano-quantum fluids, supporting internal vortices, coherence eddies, and structured π-flow cascades. This article develops the mathematical foundations of nano-turbulence, characterizes its structural origins (aromatic networks, hydrogen bonds, curvature funnels), and discusses its functional consequences for allostery, mutation sensitivity, catalytic efficiency, and quantum energy transport. To the best of my knowledge, this is the first formal scientific proposal of nano-turbulence as a biological phenomenon, establishing a new paradigm in quantum biophysics.
