Abstract

We examine the effect of physiological cations Na+, K+, Mg2+, and Ca2+ on the mechanical properties of bundles of λ-phage DNA using silicon nanotweezers (SNTs). Integrating SNTs with a microfluidic device allows us to perform titration experiments while measuring the effect in real-time. The results show that only for Mg2+ and in particular, at the intra-nuclear concentration (100 mM), the interaction occurs.
