What is it about?
Our methodology exploits the vibration dynamics of a single nanotube, which changes with the velocity of the fluid transported inside it. We propose to determine fluid velocities based on knowledge of the bending frequency spectrum of a nanotube with a stagnant fluid inside it, and of a nanotube with a moving fluid whose velocity should be determined.

Why is it important?
In this work, we develop a theoretical framework that promises to determine flow velocities with uncertainties much lower than the ones reported for conventional methods in the literature.
Perspectives
Our work might constitute the basis to propose a wide range of experiments of flow across nanostructures in different experimental situations focusing on frequency measurements that overcome the uncertainty limitations of conventional flow magnitude determination methods.
