Stretching of tethered dna in nanoslits

WebJun 29, 2024 · An alternative way of stretching DNA in nanofluidic channels was presented by Matsuoka et al.28 They used PDMS to make nanochannels where DNA and chromatin can be fully stretched. Since PDMS is a soft material it is possible to vary the size of the channels by varying the strain of the material. WebFeb 1, 2024 · Towards the end of the translocation, DNA segments faced a weaker retarding force due to the lower amount of DNA residing outside the entrance, thereby yielding higher translocation velocities. The weak forces involved in the translocation process did not stretch the DNA during translocation but allowed folds and knots to persist inside the slit.

WebExternal forces and confinement are two fundamental and complementary approaches for biopolymer stretching. By employing micro- and nanofluidics, we study the force–extension dynamics by simultaneously applying external forces and confinement to single-DNA molecules. In particular, we apply external electric fields to stretch single DNA molecules … WebApr 17, 2007 · The nanoslit geometry, however, physically confines polymer molecules to two spatial dimensions; further reduction in configurational entropy resulting in axially stretched molecules arises spontaneously and appears to be electrostatically mediated.
