Assembling nanostructures from DNA using a composite nanotweezers with a shape memory effect
The article demonstrates a technique for fabricating a structure with the
inclusion of suspended DNA threads and manipulating them using composite
nanotweezers with shape memory effect. This technique could be suitable for
stretching of nanothin DNA-like conductive threads and for measuring their
electrical conductivity, including the I-V characteristic directly in the
electron microscope chamber, where the nanotweezers provide a two-sided
clamping of the DNA tip, giving a stable nanocontact to the DNA bundle. Such
contact, as a part of 1D nanostructure, is more reliable during manipulations
with nanothreads than traditional measurements when a nanothread is touched by
a thin needle, for example, in a scanning tunnel microscope.Comment: To be presented on IEEE 3M-NANO 201
Ti2NiCu Based Composite Nanotweezers with a Shape Memory Effect and its Use for DNA Bunches 3D Manipulation
The DNA molecules were controllable deposited on graphene and thin graphite
films and visualized using AFM. The mechanical micro- and nanotools, such as
nanotweezers with shape memory effect controlled by heating were designed and
tested. A technique for fabricating a structure with the inclusion of suspended
DNA threads and manipulating those using composite nanotweezers with shape
memory effect was suggested.Comment: arXiv admin note: text overlap with arXiv:1811.0294
