Modern photonics requires technologies for the reproducible and controllable production of nanostructures, since many interesting and important optical processes occur on the subdiffractional scale characteristic for such structures. However, working with light at nanometer distances requires nanometer precision in object positioning, which is extremely difficult to achieve using standard methods. One of the new approaches that can become a response to this challenge is the use of DNA origami: structure of the polymer DNA molecule allows, on the one hand, chemically “tuning” of its geometry to obtain arbitrary shape on a nanometer scale, and on the other, addressability of DNA molecule allows nanoobjects to be placed at any position along its chain. This review considers some practical issues related to DNA origami preparation.
