    Abstract

    We report a low-pressure microfluidic deoxyribonucleic acid (DNA) fragmentation device based on a combination of me-chanical hydrodynamic shearing and low temperature sample heating. Conventional DNA fragmentation based on hydrody-namic shearing is capable of achieving fragment lengths (FL) < 10k bp with pressures ΔP > 1 bar. The application of a small amount of additional thermal energy to the buffer medium results in ~10x reduction in pressure requirement resulting in FL~6k-8k bp with ΔP~1-0.1 bar with sample temperature Ts~45º C
