## Abstract

DNA detection is of great significance in the point-of-care diagnostics. The stiffness of DNA, varying with its sequence and mechanochemical environment, could be a potential marker for DNA identification. The steric configurations of DNA fragments with different stiffness were simulated by employing the Kirchhoff theory of thin elastic rods. We identified the stiffness of DNA with the trained convolutional neural network on the simulated image set. The identification accuracy reached 99.85%. The stiffness-based identification provided a promising approach for DNA detection.
