The conformations of one end tethered and two ends tethered DNA are measured in different temperature gradients up to 3K/μm. The results show that temperature gradient can exert force on a single DNA and create internal tension within it. The magnitude of the force is of the order of 0.1pN and is enough to manipulate and stretch DNA. This new way of manipulating DNA requires no beads and provides local control, while none of other methods can satisfy these two requirements at same time.
